I purchased a tubular front end (with coilovers) for my CR from Tom Beroth in 1997.
It also came with the large Ford Granada disc brakes. 450 # springs were fine with 351W. I eventually removed the front sway bar altogether.
You can do a search of this forum for "Tom Beroth" and find many post and comments on his products. Also, see:
