Just in case it will help you. I have a Rockwell 15-665 floor model that someone had cut the pole to 50." I finally found a full sized one at 66." Being delivered soon though it wasn't cheap.
So now I have a spare 50"x2 3/4.
Not full length, but it's a tweener. Make a short stand for it and your full height. The way the press sits now, a short stool or mechanics seat puts you in a working position, though you're a bit low.
PM me if you're interested.
