Here is link that is interesting. Now if can be converted to rear wheel drive. This one is with 5-speed. Found another link for a automatic. Just a plain bolt in. Hum. SHO + Mustang = maybe interesting. From what read exhaust is major restiction in them. And a few have been turbo'd. Getting more interesting. Wife would like a convertiable mustang. I like the 4-eyes. Do I smell another project. Oh me, me.
