Thanks for all the info! I definitely will be getting a shop manual. Will also take a closer look to see if it is a bushing or not.
Got the brakes fully removed from chassis, hard lines and all. Was planning get it back together this weekend :-( not now.
The vendor tells me that there is no difference, 15/16" = 7/8"... yeah right.
Anyone have a good source for a true 7/8" diameter kingpin set?
