I have a '67 with a 5 1/2 inch suspension lift I bought a while back without the front drive shaft installed. When I went to install it I found that the shaft does not have enough play to accomidate the lift. With the front U-joint bolted up to the front axle the mating surface at the transfer case is only about 3 mm max from bolting up. Should I rotate the front axle? Any other suggestions?
