Looking for information on PTO to mower deck drive shaft. Local Kubota parts supplier ordered replacement U-joints P/N 70720-32110-620. The new part is SLIGHTLY larger, the bearing cup OD is 20.5 MM. The yoke is 20MM. The cross joint is also larger the the old cross joint. IF installed the larger cross joint would not have enough space to allow the cup retainers to be installed. The supplier reordered to confirm P/N and packaging to be correct. We have also talked with Kubota parts confirming this is what is in use for this model deck. RC48-62H. Anyone run into this problem before?? I have pictures and can supply measurements...Thank you
