I was hoping somebody could give me the center to center measurement on the upper control arms in the rear. From the center of one bolt hole to the other ball hole is what I'm looking for thank you in advance

I cannot VERIFY this as it is unofficial, but I have it written down in my NOS parts stash descriptions as 11.25" center to center. This is for the ZERO offset upper control arms, rear. P/N 10000076. Again, not verified. I can't recall if I ever measured them or I got that data from a tech source somewhere.

Making your own or adjusting some D.A.s?

Give me about 30 minutes and I'll send you a pic of me measuring mine on a '78 Cutlass.

Alright, measuring from the outside of the rear bolt head to the inside of the front bolt head on the rear upper control arms of my '78 Cutlass measures 11.25", just as 69hurstolds has written in his notes. IMG_20231108_130314747.jpg
It's a horrible picture but 11.25" is correct.

The rear lower control arms measure 19.25" center to center. IMG_20231108_125526427.jpg

No problem my friend, many people have helped me over the years and it's my pleasure to put some good back into the world.
