i'm new to this thread. seems like an awesome project.
brakes/wheels: have you looked into willwood? i'm not sure the model name but they have a fairly new caliper out that is made to be stuffed it in a smaller rim. give todd at
tce in tempe, az a call.
have you had your exhaust made yet? if not, i would love to help you out with that. headers would be more difficult, not sure if i could gather enough time for it. but from the header back i can do. i have acess to a tig welder, and i've done summit-cut-n-weld mandrel bent tubing before. although i don't think summit has stainless tube, i know where to get it.
