Modified 1974 Duster rear bumper

Mine is one of those early '74s with standard steel bumper brakets up front, no shock absorbing device, just the bumper gaurds, which I'm not putting back on.

In the back mine has the 2 shock like pistons with the inner bumper.

I'm going to try BurntOrange's suggestion and try to drain/compress the absorber permanently an see if I can get it to look nice without the rubber filler....
