Yep, that is the correct fitting for the big block A-Bodies, it came on no other A-Body AFAIK.
Dave, looks like a fun project, can't wait to see it. I have parted out well over 300 A-Bodies in my life, so if you need to bounce anything off me, please do so!
The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
