For those that have converted to a Ford 9 inch, while running a 727. What U joint are you using or is there in adapter style one that will let you use the 727 shaft and bolt to the 9 In pinion yoke?
ThanksDenny's Driveshaft has any of the combination u-joints that you might need. The Ford 9 yoke most likely is a 1330 or 1310, to your 7260 or 7290 driveshaft.
