Didn't actually do anything to my van, but did do something for it. I grabbed a bigger (3.75" dia. vs. 2.5" stocker) driveshaft (free-from '73 C-class motorhome) for the rear axle swap (8 3/4 from '73 Maxi to replace JJ's puny 8 3/8").
Might have been a waste of time since it still needs to be shortened, but stripped the rust off and shot some satin black on it.
I expected tiny 7260 u-joints on JJ, and wasn't real surprised to find them on the Maxi, but considering the size of the driveshaft and 7,500 rear axle (Dana 70) rating, I was shocked to find them on the motorhome.
At least I'll save a little cash on that part of the swap...
