I know its been asked before, but here it is again. The ride on my 59 leaves a bit to be desired, so I am looking to get it a little more street worthy. 2 pumps, 4 batts, 2 ton springs. Also, what else is needed besides the actual accumulator? Where in line does it install? I have heard mixed opinions, some guys said they dont help at all, some say they make a world of difference. Do they come charged?
