Yeah, I was looking over that earlier, had a couple questions about that that I found answers to on this thread...

So this is what I'm looking at, part numbers match to what the 6066 guys listed (although on Jeg's site on the item description for the adapter plate it says "Large Holley 2bbl to any Rochester 4 bolt 2bbl"). A couple people in the above used that adapter plate with no issues. Some people bolted everything up with no issues, a couple said they had to run new choke cables or fab new accelerator brackets but aside from that it was just a matter of bolting everything up.
