I think my biggest hurdle is going to be the kickdown. Its pretty jenky right now. I might could bend the rod a bit but its totally out of alignment as is.
I managed to make use of the 2-bbl brackets, cable and KD rod when I converted my old 1988 Fifth Avenue (M-body with a 318) to 4-bbl but I would not recommend it; it took a LONG time to finally get everything lined up and I had to finagle all the parts a bunch. Not worth saving the $80 or whatever, IMO. Plus you run the risk of burning up your trans if the KD isn't adjusted just right.
