Thanks again for the help. I've decided after doing some reading that I'm going with the Blacktop ZC. Now that said I'll need the following correct?
The 30020 and accessories it comes with
A wiring harness adapter for the MPFI and my harness
A tranny, (how much for your shipped to 75554?)

Is that it? Will my axles hold up or do I need new ones?

Again thanks for all the help I'm really starting to understand these cars more with yalls help and reading old posts out swaps.
