All things considered, it looks like my self image took the most damage
So my best guess, considering the straps are not torn, and that all my bolts are still there, is that I missed a bolt hole. The built in washer pinched the strap, holding it for multiple test drives, tricking me into thinking it was done. Big time torque was all that was necessary to rip the driveshaft loose. What can I say, freak accident? Crit fail on intelligence? Gonna blame working on jackstands in my driveway, it results in doing alot of stuff blind. Got some new moog high strength u joints (non greasable), new straps and bolts. Floor looks like it can be pounded into shape, I don’t have a welder but brazing has been working good as a temp fix. Think I’m gonna get some plates welded on before I have any rear passengers.
