Hi all
I have a 67 deluxe with hydro, and the subframe from a 70 K (dry).
The 2 subframes have different size top mount nuts.
Hydro with 5/16 UNF & dry with 3/8 UNF.
Is this correct or have the wrong size nuts been put in the hydro subframe?
Also should I stitch weld around the top mount plate even if it has no cracks?

deleted everything - utter lunacy!!

So, can I get studs with 5/16" both ends?
Or, look at if it is possible to remove the 5/16" nuts in the subframe & replace the with 3/8" nuts?

ahhh!!!! sorry!!!

anyone reading my post above would think I'm a complete loony!!

hydro subframes used 5/16" bolts through the crossmember, dry subframes used those stepped 3/8" to 5/16" studs

go to a bolt place and buy a big long unf bolt... I'll give you the size in 5 minutes

the hydro subframe bolt is 4 1/4" long (without the head) of that, the first 1" is threaded.

a while ago I bought some high tensile ones at my local coventry fasteners that did the job, I have several of the original ones too




sigh... I've got a mind like a steel trap, rusty and squeaky

cd,
There's no such thing as a 70 K dry subby, they were all wet. If it's got studs either the subby is from something else, 850, van or whatever- or the bolts have been replaced by studs.
