One wire lock-up, 4 spd automatic w overdrive into A-body.
Before I bought my TCI adapter I called TCI and Wilcap to find out which one was the thinnest so that it would minimize the amount I would have to cut off my cross member (substantially weakening that side) . The Wilcap people said their adapter was 5/8" thick while TCI said their's was only 1/4" thick. I chose TCI for that reason. If the Wilcap is actually 5/8" thick be prepared to cut a substantial amount of metal off the passenger's side cross member and the whole section of the driver's side. In the pics I attached you'll see the driver's side and you can also see how much I had to remove. If the Wilcap is 5/8" thick you will have to completely remove the section that the arrows are pointing to. You will also have to remove approximately 1/2" of the opposite side of the cross member (passenger's side). Just my opinion, many members prefer the Wilcap because it doesn't require all the cutting on the plate. But since my labor is free I didn't mind at all.

sounds a lot faster to just trim the old style adapter plates to me.
this one is sounding better and better...
