If you go with the Fiero 5 speed manual then you can reuse the tranny mounts and axles and just need to make an engine mount and dog bone.
If using the 4T65E HD tranny that comes with the 3800SC engine then you will need all mounts, both axles, dog bone, shifter bracket and lever to make the Fiero shifter and cable control the 4 speed auto tranny.
Either way you will need a swap harness and PCM as well as an exhaust system, better fuel pump and fuel lines.
