The engine is also back in and I have confirmed that the change I recently made to the radiator tilt position provided a big improvement in clearance between the radiator hose and thermofan. Even with this change, I still would have needed to trim the thermofan cage (as seen in below photo) but the radiator hose no longer fouls on the cage.

I lastly made a short length of the ground cable to the body.

Really nice work and very creative problem solving, but you might have created yourself an earth loop there - it can screw around with electronics - the kind of problems that just don't make any sense... like temperature gauges reading wrong at certain RPM, coils firing at the wrong time, squealing through speakers

Your battery is earthed in the boot floor, and then again at the front subframe and again to the body so there are 2 earth paths from the battery to your subframe. I think you should isolate it in the boot the same way as the 12V

I assume you plan to use the subframe earth point as your "primary" earth point and go off to everything in a "star" layout from there, in which case, good plan ;)

Thanks! You are dead right about the ground loop and I forgot to consider it as a potential issue (even though I've encountered it before in circuit board designs :oops: ). I've had a talk to an auto electrician and he has confirmed that ground loops can definitely introduce unwanted electrical noise and/or sensor voltage errors, and that connecting the negative battery post to the body shell is the safest and best common-ground point for sensitive electronics. In light of this, I will remove the entire ground battery cable and the battery will retain the standard configuration where the negative battery post connects to the boot floor via a short cable.

I wouldn't remove it, I'd keep it the way you've done it and insulate it away from the boot floor.

I doubt you'll get any serious voltage drop through the long cable, but it does eliminate the voltage drop we get through 50-60 year old spot welds... and you'll have a really clean earth source for your ECU

I hope its labelled REAL clear in the boot which cable is which! :)

As per the other cables I've made, I was going to have red/black heat shrink to aid in identifying the cables. Good point though - I might even use red sheath for the 12V cable within the boot.

After the feedback about ground loops, I've made a second through-panel connector so that the ground cable is not attached to the boot floor.
Image

I've drilled a hole near the factory battery ground point and the negative post of the battery will join to this new connector. I'll extend the ground cable under the car (using a butt connector and some spare cable) and route it around the battery box to fit to the new connector under the boot floor

I have previously made some mounts for my seats that I will be using but the biggest issue is that because I'm tall, the seats had to be moved further back and fouled against the rear storage bins and therefore the seats had to be moved inward towards the centre of the cabin. The problem with this is that with the large seats, they near enough touched which made it a bit squishy when both drivers and passenger were seated

I decided that the bins didn't need to be removed, just moved. I cut away the front of the bin and marked where the reel would be
Image

I wanted to retain the finishing trim strip that clips on top of the storage bin sides. This was done by taping a few pieces of 2.5mm steel to my vice and clamping the new steel sheet between them in the vice. By repeating this along the length of the steel sheet, I ended up with a pretty close approximation of the original lip on the storage bin edges
Image
Image

After trimming the bin-front to retain only the curved section and to the match the floorpan shape shape, I welded on the new steel piece.
Image

Everything was clamped in place and welded
Image
Image

I also wanted to make a cover for the seat belt reels to hide them. This was a box made from 0.8mm steel sheet that was a snug fit over the seatbelt reel. Overall I achieved an extra 40mm of room to move the seat towards the door.

Way back in 2010 (before I had the skills for repairing and welding body panels), I got a few recommendations of a guy here in Perth to do some private rust repairs (after the shell had been blasted). After a few months, I went to inspect progress and the repairs were disgraceful. It turns out he started working out of town and got his teenage son to do much of the work instead of him. This is worst stuff what I got back :evil:
Image
Image

Years on and I offer up the bootlid to see how well it (didn't) fit. The gap along the bottom was not even (non-existent on the left; large gap on the right)
Image

The right hand boot hinge holes no longer aligned with the bootlid holes
Image

The panelwork under the boot was poorly deseamed and the bootlid stuck out 10mm!
Image

I got a another guy to fix most of the dodgy work but at the time I couldn't source a decent rear boot panel so those repairs were limited. I recently found a guy getting rid of his rear boot section and planned to us that to complete the repairs myself however my main concern was getting the gaps around the bootlid even so I laid in some fibreglass in the boot opening edges of the good boot section before cutting it apart. This would act as my template when fitting the new panel piece
Image

First step was to remove the boot section of my shell
Image

and the replacement piece
Image

Once trimmed to fit, I used that this fibreglass piece was used to position the new piece. This photo taken from within the boot shows the huge gap and the proper position of the boot panel

The replacement piece had the hinge holes badly worn so I welded in a new section and would redrill those holes later. This photo shows the old panel that I cut out and how bad the boot hinge holes were in the replacement piece
Image
Image

and because the boot floor had already been cut short, I had to weld on a small extension strip of boot floor
Image

The new panel is now welded in place
Image

and a new beaver panel section welded in
Image

The boot lid was fitted and gaps are now FAR better than before and panels lined up
Image

To redrill the boot holes, I fitted the hinges and lined up the hinge holes so they didn't bind when opening/closing.
Image

With everything held in place with magnets, straps etc, the new holes were then drilled
Image

Looks great, maybe better than factory ;). Surprised you didn't take the opportunity to make some sneaky internal hinges.

Just a small update for now... Approval for my engine conversion from the Department of Transport (Western Australia) included a requirement to maintain all emissions equipment so the carbon canister had to be fitted. I found a spot above above the gearbox where I could squeeze in the carbon canister.

The mount for the canister was easy to make and consisted of a couple of bends on some V-shaped steel.
Image

Image

I welded this to the brake booster brace and the canister is very light so there shouldn't be a problem with it fatiguing the booster bracket. The canister is easily lifted off the mount when I have to access the air filter box and clean the filter. The fuel hoses were then cut to length - running up from the firewall area, sweeping around brake booster and up to the carbon canister/fuel rail
Image

The feed & return fuel hoses run under the intake piping and the small diameter hose from the canister to the throttle body was also fitted.
