I used coil-overs once but only on leaf spring suspensions to assist, as I removed all but a single leaf. This was in conjunction with traction bars to allow dialing in traction a bit. I agree the kits available to drop the 63's are great and require almost no work. I do like the look of a set of coil-overs from the rear giving it kind of a bucket look.
Pictures for sure if you decide that route.
Incidently I am on top of the fence having added a 2" body lift for a 3/4" stance.
