rear shackle length firebird
My firebird has longer than stock rear shackles to counteract the 33 year spring sag. I just put new springs in it and it now will clear 30 inch tires with room to spare, ( looks a little to 70's ).
I plan to shorten them up and was wondering if there is a minimim length. They are 5 inches between bolt centers now. thought I'd try about 2.5 - 3inches. Will this be too close to allow the suspension to work properly?
Thanks for your help
