Trendsetter Sidewinder end caps ARE available from American Performance in Coco Florida, $38 each. I just ordered a couple pair, not sure if they are the "hand laid fiberglass" repops or plastic as the originals were. I already had a new set of repop rails & shields from early 21st century & the original REAL-DEAL ones that came on my '71AMX, which need a littleTLC. The repop rails don't have the black centers like genny's had, so I'll be painting them & some screws. I'll be having the ONLY 2012 Hemi Challenger with Trendsetter Sidewinders in America!! Will I take the resonators & tailpipes off & run the exhaust out the side? MAYbe...I would say that there is a small fortune to be made by bringing them back into production for today's breed of musclecars...for someone....
