With the T5 the main issue for you would probably be that the shifter is a couple of inches forward of where it is on the FOG and you would have to cut your trans tunnel, and make sure there isn't interference with anything else on your car. There are a couple of other mods, the main one being with the crossmember, but since your's isn't a Pinto that is something else you would have to look into. There have been a few discussions about this here.
I don't really know anything about the T9 conversion. There ought to be some stuff here somewhere about it.
The Ford Ranger trans bolts up, but the shifter is way too far forward for Pintos and probably your car, along with other possible problems. On the Pinto the shifter would be hitting the dash.
I was hoping maybe a real trans would work, like a Toploader or Muncie, but seeing as I am stuck with the 2.3L like you I don't think we have many other options.
