I would call Saleen directly and ask if they have a rebuilder they recommend or if they do it in house , not sure , or you could watch Ebay for used units
I remember checking out those saleen kits in the past, at that price would it be a better decision to go with a Kenne Bell kit? I know KB offers a kit for a similar price, but would there be an advantage to one manufacturer or the other?
not sure about the advantages and disadvantages of each but i personally like the kenne bell. but since you have a saleen already maybe you want to keep the stock look and get a saleen sc to match.
