I forgot to blog about this, after months of waiting and back and forth and sending multiple old shafts, waiting for me when I got back from Thanksgiving trip was the box from The Drive Shaft Shop. They ended up manufacturing everything except the wheel hub cup. All from Chromo/300m steel. 300m is a slightly different alloy of 4340 chromo and features higher strength all around. Looks good, although missing the dust shields on the transaxle side.
Installation of the short drivers side went without a hitch. The long one gave me problems, the little spring clip retainer was not seated correctly and I ended up mangling it trying to insert into the transaxle. It took me a bunch of trips to Napa to find another. Had to find different nut also, the one they provided was made for the style where the shaft has a notch and you punch the flang of the nut into it to lock. I needed the nut with locking castle type washer and cotter pin. It’s finally in, driving around the neighborhood, they work. No race for a while though, so I don’t know how they’ll perform. Odds are these shafts won’t break. I hope so because with the single piece transaxle side cup design, it’s not as easy to change.
