Thanks to all who replied, I have a beter perspective on this now.
Thanks for the welding advise Bill S.. Although I will have a good
welder do it, I'll make sure they take this into account.
Did some angle measuring last night and found out the the stock pinion
angle is up 2 degrees and the TC output is down 2 degrees. The
operating angle of the stock DS is right at 10 degrees (12 degrees
from the floor). Also, based on trig calculations assuming a super
short SYE will be used, the plan is to:
1) weld the perches so that the pinion points up 8 degrees from
parallel to the floor
2) shim down with a 6 degree shim untill the lift is installed
3) once lift is installed, shim the opposite way to get the required
angle, looks like it should require less than 6 degrees even in the
worst case
4) use a regular CV style DS (one u-joint at axle pinion and double u-
joint at TC)
Does this sound reasonable? No issues with 6 degree shimming?

Just remember that you want the static angle on pinion a few degrees
more in opposit direction than one on Tcase because the axle will
wrapup and reduce the angle on the pinion from axle torque with a leaf
spring suspension. Sometimes several degrees. THis is why some get
vibration at certain loads and speeds and cannot figure out why.
