[jays 1971]

I've done 2 sets of the basic conversion kit from stainless steel brake corp. There are a few different kits available depending on what you want. I found the kits very easy to install and they work very well. One set on a 70 and the other on a 71. The kit I have is designed to fit inside a 14" rim but the specs are all on their site. Hope this helps.
