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.

 

I believe they are wheel studs

 

Do you carry these longer in lengths?

 

I do carry some that are 10mm longer.

 

Fitting an early control arm to your later car?

 

What's the total length?

 

80mm

 

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.

 

How much? Do you know the exact size of the original?
Reason for asking I want to make sure I have enought threads to hold the bolt.

 

The original's are 72mm and the 80mm are $15 ea.
