The great part about it in the 80's and 90's was that the cool parts were cheap or free! As people restored the bikes they pulled off the Flanders, Hellings, cut fenders, cool exhausts, Thoro shifts, B&H shifters, etc. and practically gave the shit away. I was labeled a "Dumpster Diver" at more then one swap meet as a youngster.
Anyway back to this particular Knuckle. Thom took this bike apart and began a rebuild, a year or so later (still early 90's) and I ended up buying it from him as a basket case. The motor is the one that is in the 41 Knuck TT bike I am building now.
Oh yeah...the cut down rear fender that was on this knuckle is a pan fender and is now on my 57 "Black Jersey Pan" (Apehanger). Re Cycle ing!
