'02 LS1 F-Body into a '92 c1500---

The right side exhaust manafold would not fit. It interfered with the rear upper A-arm mounting bracket.
I purchased an '02 5.3 truck manifold which cleared the bracket.

However:

I had to slot all three mounting holes on the pre-cat for it to bolt up. Pre-cat is stock, off the F-Body 5.7.
