? About upper A-arm shims and bolts, 1985 Cutlass?

12mm sounds right. Are your stock bolts in bad shape? I ask since the stock bolts have a 'tab' pressed onto them which prevents them from spinning when you remove the nut. It would be difficult to get a setup on the bolt head to back it up.

Yeah mine are not the best looking...and the guy that helped me used an impact on them to take them out...so they are blown out. I figured id just get something new and use a friend to hold the backs while I tighten them..even the ones on ebay do not have those notches/tabs. It's not that hard to get to mine as I can easily pop my spring out since I have hydraulics. 🙂 I'll get some grade 8 12mm bolts, having to shim them you guys think a 2" bolt will be long enough? Also thx again for the shim link...my local Merels Auto had a box of them to be today for $14 for 50!! Same ones you posted!

Glad I could help on the shims. Yeah, I think 2" will be long enough. That translates to 50mm long. Make sure they are stamped 10.9 on the head of the bolt. That's the grade for a metric bolt with a tensile strength comparable to a grade 8 bolt.

UMI sells a bolt package that is what I used on my car since I didn't have the stock bolts left
