Post subject:  Welding in a new front passenger floor question

Hi everyone,

I am going to embark on replacing my front floors - the car looks like the Flinstones car right now.

I am interested in how I should tackle the welding.

My thoughts are:

Close to firewall I would do plug welds
Everywhere else I would tack and do butt joints.

I hope that my question makes sense. I just wasn't sure if when using the patch panel you would need to use plug welds anywhere else.

I wouldn't plug weld it. I would overlap it 10mm at front and seam weld it with MIG so it's weatherproof.
On top, and MIG underneath the lap too if it's on a spit.

Out of curiosity, was that how they did it from factory or is that the way it should be done now?

From memory I had to remove the spot welds to separate the original rusted floor from the firewall.

As you have described is the way I would do it.

Factory was just spot welds with a little bit of brazing here and there. And a touch of mig in a couple places )like where the floor pan joins the inner wheel arch just below the seatbelt strap door retainer). But put together with a spot welder.

They were then tarred over the top of the seams and then painted over the top

Whether this is the right or wrong way to do it, that's exactly how I did mine, both sides.

Overlap and seam weld top and bottom. Mine also done this way 10 years ago and still perfect.

68auto where did you get the floor repair panel from.

The image shown is just one that I found doing a quick Google search that would demonstrate what I was talking about.

The panel I got was probably from MiniSport (Aus). I needed an Aussie panel as the car I am working on is a Mini Matic.

For cars `67 to `78 you need the Oz `hydro' panels. Also available from Karcraft, and Minikingdomonline.
