guys on in that thread I linked to- they claimed that some of them came with smaller u-joints though. I as well believe if it originally came with D50 then it MIGHT work.
Definately all Ford F-350 but I am not positive on F-250 as they came with TTB with either D44 or D50. The correct years of ford trucks to rob the parts to do this would be 1992 to around 1997? basically any years the ford trucks came with servicable wheel bearings before the Super Duty come out which came with the unit bearings.
