If you need any details or photos, check out my build thread. I just finished converting my car (part of a full restoration), there should be some good photos in there that can help with how it all works and how i made it all fit (some custom fab required). I also have more that i havent posted if you need help.
"The Hobbler's" rack mount is what i used, and it is darn near a perfect install (some slight modification to clearance the fit of a dual master brake cylinder), and i custom made special spacers for it instead of using the supplied spacer.
I had also bought the solid mount option (original 126 brackets) if i decided to not use the bolt in bracket. But the bracket ended up working great.
With it you need a 126 rack, and the rubber mount bushings for the 126 rack, along with the tie rod ends.
Racks and steering arms can be harder to find. i got mine, new from Axel Gerstl. They have been great, although slow, when shipping to Canada. likely the same case to the US. UK suppliers might also have the 126 rack in stock.
also.. we gotta know more about the beast you have built there. Very cool!
