I just did a quick google after looking at the kits from Exotic. They appear to be a modification off of the
PSI Football kit. I -think- the tolerances of the middle bushing (which would be the two from exotic's kit) are -close- ...(Look at -
this-
kit for the bushings.
If Ed & Dawn aren't responding from Racine, then you might want to get Ryan & Pat a holler at Woodturningz. (They're in Noblesville if you weren't aware) From what I can tell, most of these specialize kits come from a small number of factories and are pretty
much using interchangeable parts --especially bushings (why recreate the wheel when the hub caps are all that get changed?)
Just trying to be a help...
