I acquired some parts with a project I purchased. The seller told me what he thought some of the parts were, but he was wrong on some of them. I am now trying to confirm whether or not the front upper control arm I have is for a 1984-87 Corvette. It looks like it may be what I was told, but using Google I was unable to match either of the numbers to a specific part. The wishbone piece has the number 3126409 stamped into it and the characters 1 <> R cast into it. The mounting bar has the number 19991 stamped into it.

If anyone can help me positively identify this part using numbers or dimensions, I would appreciate it. I can post pictures if that would help. Just tell me what view is needed to identify it.

For early thru '87 uppers I believe the "flats" of the shaft are parallel to the ground and '88+ the "flats" are vertical to the ground. By flats I mean the surface between the mounting bores to the bolts.

This I believe is early

This I believe is late

I have several "late" no early - I believe that difference was intentional as an identification procedure in manufacturing. Confirmed? NO

Go to eBay and use various images to likely ID any other parts you might have questions regarding or just post snapshots.

Thank you. I can work with that.

I'll confirm. My '84 has "flats" parallel to the ground (p/n 16371). My right A-arm p/n 3100203. The c-c on the mounting bolts is about 6 3/8" (hard to get an accurate measurement). I believe the later arms have a different c-c.
