Hey so long story short, the driveshaft shop sent me a driveshaft with a 4.10 flange on it. I have a 3.90 auto diff in my FD.
I called them they sent me another flange and its still wrong. Does anyone have measurements of the bolt holes etc on the auto 3.90 that I can give them? So I can finally get the right parts?
Thanks guys!
BTW: I got 2 7/8 bolt hole to bolt hole. Does that seem right?

Why can't you send them the measurements from your 3.909?
If your car is a STD trans, why did you not swap flanges when you swapped?

Many missing facts.

Its a long story. I don't want to publicly bash the vendor yet.
I have a TR6060 from a new camaro in it with a 3.909 rear diff with a KAAZ unit. I bought the trans driveshaft diff combo but they specced the driveshaft wrong. I just need the proper flange. The diff is in my car so measurements are difficult. Was trying to see if someone has one on a bench or has had this issue before to help out. I measured 2 7/8" bolt hole to bolt hole from underneath the car but want to verify as stated above.
What else do you need? I'm trying to save myself from having to buy yet another 90$ in KAAZ fluid to get this issue worked out..

Billyboy thanks! That'd what I was looking for. Didn't come up in the search on my phone though...
Called driveshaft shop today they are sending me another flange. Hope to be tight this time!
Thanks again!
