I'm dropping a Vortec 454 and a 4L80-E into my 89 Silverado RCSB and have decided to use polyurethane mounts. How does the two-piece transmission mount go together? I've seen it done (on the net) both ways as pictured below. Which is right?

If it goes together like the stock mount, the top one would be correct, though mine is just one peice and rubber.

You are matching engine mounts and trans mounts right? Meaning poly at both or rubber at both.

Yeah, I'm matching the mounts. I have polyurethane engine and transmission mounts. I got some good directions in to box for the engine mounts but there is no transmission mount directions. They are the Energy Suspension mounts.
