short version of what i tried to post with that pic
use a inclinometer ( get an app for your phone ). and measure your block, that is the degree shim you need to bolt to your spring pack.
nonCV driveshaft requires a 2* pinion down shim.
from your pic i am guessing CV driveshaft is about 4* UP
will be curious to see your measurement

Well I just measured it, and if I'm doing right it looks those blocks would tilt the pinion up about 3* Maybe I won't need the shim at all. I'm thinking the spring perch has the angle built in, and the blocks mimic it. What say you?

no, sterling fixed the perch angle and ford used various degree blocks depending on wheelbase.
with a non CV driveshaft. the goal is to be within 1/2* of parallel and the further out you get the worss the vibes.
i do not know about the CV driveshaft but i sense you are about to find out. lol

full droop ? 0*. ?
what was at 0* at full droop ? i am not aware of any angles that need to be 0* at full droop.
important things at full droop would be driveline length, shock length, brake line length, air bag length. basically make sure the springs and shackle are what is limiting droop and not anything else

I'm in over my head at this point. I just hope I can bolt the right stuff together to make it work. My Ex has a very smooth vibration free ride on the freeway, I hope I can keep it that way. I'm sure having that double cardan at the transfer case will help.
