Default Upper A-Arm
I've search the forum but can find what I'm looking for.
Does anyone know the dimension on the studs the hold the front upper A-Arm?
Lenght, thread pitch and so on... Need to replace mine with a longer one 5/8" to be exact.
Thanks in advance.

Why?

It will not be easy though. It's not a simple bolt as you know. They're pressed thightly into the arm, you'll probably need to do some smithing.

Yup, I swapped the stock pieces with bolts.
I used 70mm long, 10.9 grade hardware.

I also put the bolts through from the engine bay side.
Now I have the nuts in the fenderwell and can zap them off with an impact without having to touch the inside.
