1995... look for a 1995 GM unit. The NV3500 clutch cylinder will swap right over. 1994 and earlier will have the super low 1st and wide spread between 2nd and 3rd. 1996 and later use a different internal style clutch release. You can use a dodge unit, but you will need the Advance Adapters bellhousing... The 1995 will also have the later shift tower.
Here is how to visually identify what you want to look for in the chevy NV4500
bellhousings
1992-95- have the housing on the lower passenger side for the external cylinder
1996+ has a large cut-out in the drivers side for the hose for the internal release
NOTE: bellhousings are not interchangeable. Case to housing bolt pattern is different.
top covers
1992-94 shift lever has the same style retainer as the SM465... round spring locked cam
1995+ shift lever housing is removable. It is square with 4 bolts. This top cover also solved the 3rd synchro failure problem.
NOTE: top covers are interchangeable
cases (bellhousing removed)
1992-95 input bearing retaining plate has a collar for the throw-out bearing to ride on. Use with external cylinder style bellhousing
1996+ input bearing retaining plate has NO collar for the throw-out bearing. Use with internal style bellhousing
One more thing... you shouldn't have an issue with this since your t-case is further back, but when I was mocking the NV4500 up in my 70 (married 205) the driveshaft was VERY close to the boss on the bellhousing for the external cyl. how does yours look? The 3500 and 4500 release cylinder housings are identical.
