I have a model 20 case. Will a th350 4x4 tranny bolt up to the 20 with out adapter? Or can i put a chevy case in the stock position on the cj? Need to do this on very limited budget any advice will help thanks.
The TH 350 was never offered bolted to the Dana 20 in any factory applications.
In fact Nothing will bolt to the Dana20 without an adapter........it's just that some are factory adapters and some are aftermarket.
The only GM auto that was ever factory adapted to the Dana 20 was the TH400
It was used in early model Jeep Wagoneers (and in some Jeepster Commando's)
This TH400 was however only offered with either an AMC bolt pattern or a Buick pattern.... you would have to swap the Tranny case to a Chev pattern TH400
The only part time transfercase that was ever bolted to a TH350 (with a factory adapter) was the NP205....these were often found in Blazers and Jimmys in the early 70's (or in the 1980 models)...a lot of the mid 70's Chevs were equipped with the fulltime NP203 (too long to fit in a CJ)
