Welded the coupler on after hammering it down. I ended up going 6thousands too big on the shaft from my measurements on the coupler, and I could have easily gone 3-4 ish. It was TIGHT pounding that thing on there. I cut some slits up the coupler then welded those after drilling the pin hole then adding a grade 8 bolt. Ended up welding both the head and nut to the coupler too. Should be solid! Ready to install now.
Everything takes so much longer than anticipated, ESP while taking photos and videos of the process. Getting the driveshaft bolted up today and roller bearing packed. Going to work on radius rods, while out of the car and clear, then getting this setup including ebrake cable installed and back in the car. In case you’re wondering about the funky leaf spring config, will need to rearrange them with full weight of car until I like the ride height so don’t want to cut them quite yet.
Spent all day on it, but got it all bolted up, radius rods cut down, heated, relocated, tacked. Progress! Rear end is upside down in case anyone is thinking what’s going on…
