If I had the Art Carr AOD with AA kit installed that BCB sells...and I have a dana 20, will they just bolt together, or is there something else that has to be done (machining, disassembly, etc.)? The reason I'm asking is because I found a shop that sells the aod with adapter installed and they also sell the dana 20, but if you want them together, the price jumps up $200.....If they simply bolt together, I'll save myself $200.
