OEM style leaf spring rebound clips

[CamarosRus]

Dave, I called DAYTON Products Springs today.........Im working on buying the plastic pieces and steel straps, but have already been told that DAYTON may not sell individual
component pieces, but my request is getting moved up the food chain a bit..........

I have NOS Trans Am Leaf Springs (and Sway Bars) that I bought in the early 80's to install in my 70Z, but never got around to it.....These NOS GM Springs have Black Plastic Pieces with SLOTS very much the same as the DAYTON springs I have for another Camaro project...
Have ho idea when the slotted design was started at GM, but wanted to share this info
with anyone interested........
