   Make sure that the pins weren't replaced with the next size smaller ones.

I think the bushings I used were for slack adjusters if old age hasn't set in.

I don't know how I would know if they are replaced with smaller ones.  I guess I could get a micrometer and check them against spec.

buy new yokes, measure the pin, buy a drill bit....I think Clifford posted that twice... ;D

Looks like Granger stocks some yokes too.

napa does too... get new pins yokes bushing and maybe two drill bits, based on the OD of the bushing...and a drill press with a proper clamping vice.
Unless you are able to find a machine shop...
or use a hand drill, your call... ???

I have a small drill press that you use a hand drill on, but if I am going to be doing a lot of this type work, I probably need a real one.  My shop is a mess right now, so that needs to get cleaned this weekend, in order to make working through this stuff a bit easier.

   Have you actually taken any of the rods off and checked them for worn egg shaped holes? use drill bits to check for size if you have a set that goes to 1/2 unless the pins are 5/8 or larger; don't remember and manuals went with coach. You could go to Lowes or equiv for larger size bolts to check fit.

Haven't gotten as far as pulling them yet.  Probably this weekend.

Chessie, how did you know?  Pulled one today and it is WAY too small.  Why would someone do that?

   Been a mechanic forever and around  coaches and busses many years ; you see about anything over that amount of time.

Seeing as no one seems to stock the 3/4" ones and the original GMC part has been out of manufacture for a very long time, I am sure someone just slapped what they had in the shop in there.  Hopefully it will shift a little better without all of that slop.
