Ah, here it is. BII with A4LD and a doubler.
so anyway, back to the doubler.
looking at the length, i would guess that you kept the oil pump. yes?
did you go with the press two shafts together and weld them or have the shaft resplined?
if resplined who did you have do it?
As for the shaft I got it from a guy in Kentucky. He had made a batch of them for someone and he had two left over. One was sitting on his desk, so I bought it and now it's on my desk.![]()
Yes the pump is still in it.

It's a cut and resplined stock shaft. It's not one of the press fit/welded units.
The problem is that people who don't understand drive shaft geometry tend to think "funny" things. For the people who "get it", it's not a problem.
From what I can see, I bet that setup doesn't vibrate. The only thing that I would be slightly concerned about in that picture is premature wear from the extra angle. That can EASILY be fixed by running a cv/u-joint type shaft. It's cheap as borscht to buy and swap in, too.
Hopefully that works out for you. Since the shaft is hollow it becomes aweful weak when it's turned and resplined. Remember to avoid putting only the doubler case in low range.
I think you'll be ok as far as rear driveshaft length. I'd recommend a double cardian in the rear.
It's not splined over the hollow section. It's splined just past it, since the hollow part starts around the pump.
I've got an Explorer front Double cardian I plan to cut down for the rear. I've got a 4 door Explrer rear shaft I plan to cut down for the front. With the added length of the driveline I'm going to stick with a single/single shaft up front.
