Driveshaft is stock with 7260 U Joints that have the grease fitting on the end cap. Axles are Moser, spool, 3.91 gears....... I have talked to several guys about this subject and it seems there is some myth about using the bigger U Joints etc.
You would be amazed how strong those baby joints are!! Because I am cheap I ran a stock shaft up until this winter along with the 8 3/4. Ran mid 9s on the bottle and a 6.0 @ 125 boosted and tire shakin 1/8th.. lol :violent1:
