The 1.6 8V and 1.6 16V trannys are interchangeable. Depending on whether or not the vehicle had the tranny to engine braces, you may have to swap bellhousings (if you need to run the braces).
The tranny ratios are identical between them, for gears 1-4. The 8V trannys have a .86 5th gear. The 16V trannys had a .795 5th gear.
The tcases are identical/interchangeable between 8V and 16Vs (years 89-98). They do have different speedo gears in them, depending on whether they came from one with an auto or manual and depending on the axle gears. If you want the speedo to read correctly, it is best to get a tcase from a trackick that had the same tranny and axle gears as yours.
BTW, in 95 the 8th digit in the VIN will always be a U. If it is a 2 door 2wd, it will have a 1.6 8V engine and if it is a 4 door (2wd or 4wd) or a 2 door 4wd it will have a 1.6 16V engine.
