Concidentally I just knocked them out of my 49 3600 this weekend (with a 53 axle under it as it turns out).

I have a ten ton press but because the thing is so awkward I just tried my u-joint press and a slight touch of the oxy acetylene, I'm not talking colour change here just warm it up - and they started moving.

I haven't reinstalled mine yet, just cleaned and painted everything.

Yes the bushings need to be reamed I used an adjustable reamer; I do have a lathe to make alignment bushings but the one it came with worked great. Can only take a very small amount of metal off at a time which is really a good thing, but it takes a "few minutes"
