I just wanted to confirm with everyone if the rear springs on a 70 K20 are 52" and not 56". I believe the longer springs came on later models. I also saw that ORD was offering the rear greasable bushings with 1-3/4" in the front or a 1-1/2" for the front mount. I believe that a 70 K20 should have 1-1/2 but the guy at ORD that I called said the 3/4 ton Chevys have 1-3/4 diameter eyelets in the front on the rear springs. Not sure if he was confused if my truck was a later model or something or if they actually are 1-3/4" . thanks in advance. Now that summer is here ill have a little more time on the weekends to work on my truck.
