Does the tranny have a large round rubber plug in the bottom center of the bellhousing?
If so, you may have an R151, which is a very desirable tranny to have..........And which usually sell for a little more than the other trannies........
Oh yeah, is the bellhousing integral with the tranny, or does it look like it is bolted to the front of the tranny?
I know my W50 out of the 1980 4x4 is 5" shorter than my R151 and the shifter is a little more forward on it........
I can email you some pics of different tranniies showing some differences if you want to drop me a line....
