It turned out I had two separate problems. When I installed the later truck's core support mounts, they ended up at a slight angle. I was able to compensate for that by adjusting the mounts a bit and not tightening it down until it was attached via the fenders (and thus in alignment).

The second was the height - I used what Lowes calls "bearing plates" - they're a 3" square galvanized washer, which is normally used to attach sill plates to a foundation. They're about 3/32" thick, and I ended up adding three on each side of the cab at the front to get everything aligned.
