85 Vette lower control arm - can someone check a p/n please?

[qwik1320]

I have a front suspension off an 85 Vette for my Wayne Due C4 subframe...but came to realize that the lower control arms don't have a "RH" or "LH" on them. Can someone look up the part numbers and tell me which is which?

One has 3Z51 cast into it and H2495 stamped in it, the other has 4Z51 cast into it and H3068 stamped in it.

If you look at the control arm you will notice a hole on the side a couple inches in from the ball joint. It is for a through bolt that holds the shock plate onto the control arm. The hole faces towards the front of the car. I am almost 100% certain of this. However, I will verify tomorrow when I get to work.

Cool, let me know. I took the shock plates off tonight hoping there was something cast into the arm underneath...nope

Yep, that's right. The shock plate through bolt goes towards the front of the car.

Thanks Trey!

No problem. Good luck with your build.
