Any non electric 4 speed autos for a 360 mag out there?

A518 or 46RH, 46RE will work with minor electrics. Basically a 3 wire switch to activate OD but you must get them out of earlier 360 truck/jeep. Some were even used in 4.0 jeeps. I believe if you look for model year 1988 you are good but search and find the year range. Mid 90's up will not work for sure. The A518 is basically a 727 with OD. May take some minor fab to your Duster tunnel. Stay away from the A500 variants usually found behind 318's. They are much weaker based on the 904 however they can be beefed up for $$$$.

Why are you saying Jeep? And something like a 4.0 won't work because the case won't fit Mopar engines. Cases are unique to Mopar smallblock, to Mopar slant six (never made an OD for one) for B/RB (same, no OD) and for Jeep 4.0. Most Jeeps are 4x4 so the tail / OD area is completely different. Different housing and different shaft.

The main case MUST be compatible with the OD unit, you cannot just bolt an OD to an older 727, AND the thing must be hydraulic (RH series) if you don't want electronic main transmission. The cases and OD housing sections are different
