Why are you replacing the shoulder bolts? Unless they are in really bad shape there is no reason why you can't reuse them. Mainly as you absolutely will need to polish down their OD till it slip fits to the bushing as you don't want to polish the ID of an oiled bronze bushing; this will smear its pores. I polished the bolts by chucking them in a drill press and turning them at high speed with a piece of emery cloth; check the fit several times till you get a nice fit. Even if the bolts are indented most oif not all of that will polish out and even it is does not you will still have plenty of bolt surface to provide more than adequate support to the bronze.
This price may be old but it can't be that old...

The bolts were pretty messed up, maybe a little worse than the pics in the first post. You say polish them. About how many thousands are you thinking, just a couple?
Done! $58.70 delivered
installation with interruptions, 2 1/2 hours - without, about an hour.
As you said T Cro, I think I used a 3/4 deep well socket to drive them out, used the vice to press them in flush and the socket to drive them in another .350 for the seal. Again the bolts are soft. Chucked them in a drill and in about 15 seconds they looked new. It did take a little more work on one to fit the bushing but not much. I used some BG prelube to assemble. I got a work out with the grease gun, stop laughing!
Thanks for all your advice and experience.
Glad to hear that it all worked out for ya... Ya the clearance is so tight that the grease gun can barely pump the grease through...The rear is real tight now. Probably out last me. I also did the 4 led instrument lights, now it's ready for a new rear tire. I'm going back to Elite 3 bias. It's good for 20k.
