I thought that too. I was at my whits end. I had driven one whole winter without a front drive shaft trying to get one made. I was using Oliver out of North Carolina (?) and they came to the conclusion that they couldn't make what I needed. For some reason, the Tom Woods web site wasn't working with my computer at that time and I just assumed that they couldn't do anything either. A buddy gave me the phone number and told me to call them just as I was struggling to fully wrap my head around a cut and turn. The first person I talked to was Tom Woods himself. In a very calm reasuring manner he told me that it would be no problem to build me somehting that worked, and they did. In the process I talked to one of his guys who was equally smart and he told me all about how, even with a cut and turn, you never put more gear oil in your differential than normal because it causes the oil to foam, and yes, the pinion bearing will still get oil.
Call Stevo and run your needs by them. I don't think you will be sorry.
