Hi

i got 2" extensions for the rear shocks and now i am looking for longer bolts.

Does anyone know which bolts i need? (regarding to the thread - is this the correct word for it) :-/

Thanks

 

I forgot... It is for a 79 camaro

 

Top or bottom extensions? I made my extensions for the bottom pin from 3/8" concrete anchors. Just took my portaband and chopped off the non-threaded end, then put a coupler nut on the shock with a locknut, and they worked fine.
If it's the top, then I believe they are 5/16", but can't remember if it's fine or coarse. I use grade 8 bolts for shock mounting myself.

 

thanks for answer.

these are top extensions, self made.

I got also the information that the bolts could be 5/16"x18 or 3/8"x16.
My problem is, that the existing bolts are 3 different bolts, so i need to know which is original. perhabs I can rescue the inner thread of the shock mounting.

 

The nuts at the top are captured nuts, and could be replaced from inside the trunk if you're good at fabrication. Or they could be removed and regular nuts used, but then it would take two people to mount the shocks, so if you have a helper that would work.
