Good luck with the rear DM, pretty easy install!

Did you talk to Nate to confirm? What year do you have to run a 2 piece? I am running the fbody stock manifolds and they work with the 5.3 and the DM. I am running the DM up front and KP 6 link in the rear; I don't hit the cab. The 4L60e trans is very close to the tunnel, but the cab fit.
I did put new body mounts on though this 82 frame (not sure if that makes a difference).

On my old 305 and frame my drive shaft hit the back of the cab, but with new mounts and frame it is not.
