Bad Driveshaft Angles - Options?

[Notch1988]

Looking for options as I don't think I can improve my angles easily. Tranny is down 5.5, first shaft is down 7 (operating angle of 1.5), second shaft is up at 9 and the pinion will be down at 7 leaving 16 degree operating angles for the last two angles. Motor can't come down much as I've only got 1/4" clearance between the rack and pan. I've got the center bearing shimmed 2 inches and it leaves very little room to fit through the trailing arm crossmember.

Anyone have experience with the double joints used on lifted trucks? Just wondering how they are for vibration.
