Hey ya'll, haven't been on this forum in a long time. I've got a 1981 2wd 720 I'd like to lower, and apart from cranking the t-bars I'd like to get some drop spindles for the front. However every manufacturer I look at (Belltech, Street Edge, etc.) has their drop spindles listed as only working for 83+ 720s/Hardbodies. I can't imagine there's a difference but this seems weird, so clue me in. p.s. as a matter of fact there are no parts for pre-83 720s listed from any of these manufacturers, only 83+, i.e. bump stops, pinion shims, shocks etc. So again, is there actually any differences here? p.p.s. I'd also like this thread to be a spot for any other differences between 720 years to be named, because there's probably a lot I don't know!
