Here is the old bushings from an early tube with the drill marks vs the newer tube bushings .both the seals were rock hard they may have been changed once as they appear to be rubber .the bushing that gets pulled out is the smaller one and note that there are brass lining with dimples on one ,the other was pulled out from using the bushing puller and that made the rest of the bushing very difficult to get out as the jaw on the puller does not have much room to expand to get a grip.So make sure the puller has a good hold otherwise it could just take out the inner brass like it did for me.the oakie is a newer tube type and it was different manufacturer than the one that I installed (I should have used this one as it looks closer to the size as the one I used .The one I used had to be turned down a bit .Anyway the moral of my rant is that the tubes and bushings are not always a exact fit and it is best to measure a hundreds times before hammering it in as it don’t come out if it is to big and you hammer on it .Also you have to be careful hammering use a block or brass to punch it in so it does not damage the end .the yoke on mine did not fit after putting the bushing in and had to be sanded but not much.Another thing to be careful with is when you push the bushing over the splines make sure the splines are not sharp as to cut the seal.
