What driveshaft do i “need”?

Understatement of the year. Did yours just wear out or was it something on Gold Mountain?
I pinched a cap on a u joint, the one closest to the t case somewhere on Gold Mountain. I’m not sure how I managed to let the rear axle get to full droop but I’m guessing that’s what happened. I’m currently evaluating my t case choices to get a better crawl ratio. Once that is solved a limit strap may or may not be needed depending on if the problem still exists.
