Eric at Axis Driveline fixed us up with a new driveline using 1350 series stuff. The first attempt ended up just a bit too long, which he says is a much easier fix than if it was too short!
These are the same guys that built our K30 drivelines, they always do a great job.

Installed a newer-style drive line loop and I was really glad the seat pans were not welded in yet. Oh yes, I somehow managed to drop hardware in there, both sides (just cuz, I’m special
). Metco makes this loop, it’s designed for the 1st gen tunnel and was an easy install.
