Google it and several sources are selling the original Miller Special Tool for removing this bushing, several bushing installers are available too.
Don’t worry about the clearance as long as you don’t have a worn slip yolk.
Never seen an undersized new bushing yet. In our Reman process we gauge this bushing and only about 1% of the used ones are oversized.

The car has a random noise that is hard to duplicate and describe. one would almost think the cluster gear is slopping back and forth. Is it only moticeble al low speeds under a light to no load condition The drive shaft appears a bit short and there seems to be an excess amount of slop between the yoke and bushing. When taking up the clearance both directions (up and down or side to side) the noise it makes sounds a lot like the random noise being experienced. Possibly a longer shaft or yoke may all that is needed but trying to get the info before pulling the shaft tomorrow. Do you happen to have a part # or source for those Miller tools ?? Thanks a bunch

Thanks a bunch In a pinch you can use an old yolk by finding a few washers that slide on the yolk up against the radius then driving in the bushing. Just line the bushing up and start slowly. I forgot to mention you will have to knock the soft cap out of the back of the standard yolk so it will allow the output shaft to travel through the yolk to get the bushing all the way in to the support. Here are a few pics. Remover is Miller 6957. Installer is 6951.

The clearance measured at the transmission seal / boot is .035 to .040" measured with a dial indicator The drive shaft could be about 1" longer while still leaving 1" of travel. However the yoke appears fine and pushing it in the additional 1" has little to no effect on the clearance. So am I chasing a ghost or is the output bushing toast??  John Kunkle (spelling) on this board posted the specs on both the yoke, and the bushing, it was pretty tight if I recall .002-.003 clearance, the problem is aftermarket bushings are bigger, aftermarket yokes are smaller so it can be hard to fix. I have had to resort to having yokes hard chromed to tighten it up. Last one I did with bushing from brewer and a neapco yoke moves a lot, way more than an untouched original. I tell guys not to change the output bushing if it is still good, I believe originals were machined in the housing.

The local driveline shop suggests bottoming the yolk then pulling it back out 3/4 of an inch to get the driveshaft measurement... Why? Wouldn't it be easier to just bottom the yoke, measure the center to center and subtract?

Wouldn't it be easier to just bottom the yoke, measure the center to center and subtract? If the driveshaft was in a straight line you could do that...But with any combination of driveline angles for a given vehicle just pulling it out 3/4 from bottom wouldn't give a true reading for driveshaft endplay..
