The cold put a stop to my work. I got the 9" hanging from the leaf springs and the u bolts almost snugged up. I was having trouble with the alignment pins in the springs lining up with the axle perches and called it a night. My drive shaft situation will be different than yours because I am swapping in a 9" and I think the pinion is farther back than the 8.8. also because it is a truck the angle of the drive shaft will be less sever than a bronco. But never the less, if I need the drive shaft modified I will take it to Saddler powertrain in davenport.
