Hey man! Yep, they definitely screwed me over. Absolutely denied any culpability in the problems... The failure was exactly the same and the driveshafts are definitely a bodge. I’m still trouble-shooting to see if anything else could compound the issue, but it doesn’t look like it. I checked the read end geometry, the trans location and tilt angle, and ultimately I think that the shaft may be too short, or there is something jacked with the slip joint on the rear driveshaft.
And yes, I have a badass 5” aluminum, billet ended driveshaft coming from a shop I used back in my trophy truck days. Overkill, but still pretty excited.
Now I need to build a loop for it just to be really confident on the road.
