What engine is in your buggy? There were the big block Mopar, small block mopar, amc without crank sensor, AMC with cranksensor and I think that the early 80's inline 4 was some weird combination of GM and mopar. You can also get it as a 999, 998, 904, 30rh, 32 rh, and a few variations of those depending on electric lockup, valvebody lockup, and no lockup. What parts do you need? if the housing is good, then everything else is available off the shelf. Tim
