driveshafts
I have a 78 Bronco, that I dumped a 390 in. the splines for the slip in the old driveshaft are shot, so I plan to cut down a new one. the old one had a double cardan on the X-fer end. the one I'm making has just single U-joints on each end. My rear end has wedges w/ the clocks to angle my pinion up. I've heard that to run singe U-Joints both of your yokes must be parrellel because your drivesahft doesn't spin at a constant speed, and that's what the double end is for. I was wondering if this is true, because if it is, I gotta find another doub;e end.

Actually, with a single u-joint at either end they need to be in "phase" or, operating at the same degree relative to each other. However, when you are using a double cardan at the xcase end the best degree for the single joint at the differential is 0', or 1' to keep everything under a slight load.

You could go either way, since the angle at your diff is nearly zero. My advise on a double carden depends on the angle you see at the transfer case. More than 18 degrees and you should do with the carden.
