Progress on u-jointed driveshaft:
Bought one of Jute91's driveshaft repair fittings and had a local machinist press and weld a BMW 4 bolt flange onto it.
The diff and driveshaft are from an E46 front. With this flange, either the E46 driveshaft can be shortened OR a Jags That Run 1310 u-joint yoke for the BMW 4 bolt flange can be used with a custom driveshaft.
FIRST, setting up the driveshaft this way allows a repaired E30 driveshaft to be installed and removed WITHOUT dropping the transfer case or the diff.
HOWEVER, this flange is in slightly the wrong place. It needs to be cut off and moved closer to the splines (and the repair fitting trimmed) in order to clear the oil pan on the 4HP22. ALSO, the flange does not clear the transmission tunnel, which needs to be "persuaded" a bit.
Here's the repair fitting with female flange and the male flange from the E46 driveshaft:
Here's the modded E30 driveshaft with male fitting and E46 driveshaft with male fitting:
Here's the repair fitting with female flange and the E46 differential with female input flange:
Here's the repair fitting with female flange and modded E30 driveshaft with male flange:
Here's the assembly with a naked T-case sprocket:
The flange needs to be reworked to move to the right in this photo in order to clear the auto trans oil pan.
