aluminum driveshaft/ single piece

this is for all of you ext cab guys who want an one piece driveshaft or for you standard cab guys who want to switch to aluminum. While i was in the process of building my truck i want to ditch the 2 piece shaft and put in a single piece steel. While i was thinking about this i found out that newer 2500 chevy pickups come with 4" aluminum driveshafts. for $50 i went and took one out of one in a junkyard. The driveshaft is about 68 1/2" long and will have to be cut down for almost everbody. I had to take 4" off mine. I just wanted to let everyone know that if you want to change to a single piece or upgrade you can pull one out of this truck and have it shortened for a few bucks. The rear U joint fits both the 8.5 and 7.5, the only thing you will have to do is have the tranny yokes changed. These shafts are strong with all welded joints (some have crimped ends)
Just wanted to let everyone know. Pm me if you have any questions.
