Newbie
I have a 1991 chevy k1500 extra cab manual transmission I was under it the other day and found some play in rear driveshaft after taking it apart I realized something was wrong I'm working on the rear u joint at rear end the driveshaft has 1 1/16 cap size and rear end yoke is 1 3/16 they don't make a u joint like that so I'm guessing ether the rear end or driveshaft were replaced the rear end has a 14 bolt diff cover and 6 lug rims I just don't know which one was replaced
