I'm in the process of rebuilding my knuckles on my 77' and got to the point of ordering parts. At this point I'm trying to assess the condition of my spindle bushings. I've spent most of a day looking through FSMs and reading posts on Mud. Lots of statements like "replace em if they're worn" or "They last forever, you most likely don't need new ones". But nothing on a clearance limit or even and original Dia or anything. I found one post where the manufacturer of Longfields told someone .010. But that's it. Mine don't "LOOK" bad. But they currently have .010 clearance which strikes me as generous. But hell, who knows. So I'm attempting to find out is anyone has ever come up with some actual numbers for these ?
