I got a 5 speed from what I think was an Isuzu P'up, but I'm not certain what it was in. It was longer, so I needed to shorten the driveshaft, plus the mount was in a different location so I had to make an adapter plate.

The transmission mount on the newer transmission is much more robust. The original transmission mount had threads going straight in to not very thick aluminum, so it had "dissolved" on the first two transmissions (the car has 2/3 of a million miles on it, so this is the third transmission), so I'm glad to have done the work because there's less noise and vibration now. The old mount can be seen in the second picture below.

I put pictures up here:

Transmission swap

The hardest thing for you, I hear, is finding a manual transmission flywheel. Better take Robb up on his!
