I decided to start with the shortened drive shaft between the transmission and transfercase. I paid a visit to the junk yard and hunted up a drive shaft from a Dodge Diplomat. I removed the splined end and U joint from the drive shaft. With the help of a machinist at work (Thanks ET!) I cut one U-joint from the M37 transmission to transfer case drive shaft, cut the Diplomat splined section of shaft and welded the old U-joint to it.

As you can see, it didn't have to be real pretty to work. I originally wanted two U-joints in the short shaft because drive shaft theory says you need two. (I won't get into it here.) To make a long story short (no pun intended) one works just fine. The engine is off set a few degrees from center line for the input shaft on the transfer case if you are looking from the front of the truck, but the line up is almost perfectly level if you're looking at it from the side. One joint will compensate for one direction of off set, probably wouldn't work so well for two off sets.
Ok, now on to the transmission support. This ended up being really easy. I cut down a piece of 1" x 1/2" rectangular steel tubing to fit between the frame rails. I wanted to place it on top of the rails, but for alignment sake had to bolt it under. The two 1/2" holes I drilled in the frame were the only modifications I had to make to either the frame or chassis to put in this setup.

With the support placed underneath, I could put washers between the frame and the support to get the perfect alignment between the transmission and the transfercase. I picked up a block of urethane rubber and cut pieces to sandwich the support bar between. These seem to be working fine for absorbing the shocks the old mount point use to. I did have to put in a "U" to give the front driveshaft clearance.
