i am running a xj 44 in the rear with a 6 in lift and a d35 driveshaft.the yoke is allmost all the way in and i am still getting bad vibes . i also have a 1 inch t case drop , which i want to get rid of .i am planning on getting some shims and trying to figure out how to get a front driveshaft to go on the rear with out a hack and tap .i was thinking of machining out the front yoke of the front driveshaft and welding in the slip yoke . has anyone ever done this ?do you think it would work ?
