Have a C code Cal Special and an X code and both had, what appear to be, original front coil springs.
The GT/CS rode high in the nose, as they did back-in-the-day, and while staying close to original I just can't take that look. So swapped 'em out a while ago. The X code is being modifeid to a EXP500 and again sits nose-high so once the resto gets going will lilely repalce the springs to get the ride height I want.
But.... as they are orignal and I hate to throw out anything that can never be replaced by new.... is there anything about them, other than the fact they are 40+ year old parts with factory paint daubs, that should keep me from donating them to the local recycler???
