Fleetpride can die in a fire - you can read my screed in vendor reviews. :-)
I\'ve had good results with Thruway u-bolts, but mine are 5/8\", not little CJ/YJ sizes.
one small (important) correction to a pretty thorough list: a springover is MUCH more than a 3\" lift. It\'s the axle diameter (including spring perches) plus the thickness of the spring pack. Probably more like 5-6\" over what the same setup is SUA.
