Small price to pay to remove the doughnuts, I think. 2904-27 has the same dimensions, but uses a different u-joint size, I believe, so it probably works, too. They're apparently made for Dodge 7-1/4" and 8-1/4" so something stock out there shares the part.

Just an FYI for anyone who might care, or is getting sick of replacing the guibos. I'm having a driveshaft made, 2-piece due to length, for around $700. I think last time I had to ship my stock one to be balanced and a new bearing pressed on it was close to that, plus $80/per rubber. Plus the horsepowers and whatnot.
