Squat and droop, how much ?

[Wastrel]

48 Willys, 106 wheel base, 4.3, th350, 4:1 transfer case, high pinon 44 front and 9" rear 5.38 gears for trails like Moab. I ask a few crawlers and they said WHAT? I don't give a squat! I'm building this thing and I'm at the point I need to set the modified 4 links. I know how to set everything just don't know what would be a good starting spot.
