Rear driveshaft angle toyota truck

Was curious what angle others were running for rear driveshaft angle.
Putting finishing touches on 89 extra cab truck all-pro ifs to straight axle conversion. its a 5 inch lift with heavy-duty rear springs. I have already removed the factory rear spring perches. As it sits it is 10 degrees and looks about normal but didnt want to weld new perches without getting some input. Thnks

 

You should be just fine with 10 degrees, I know that you dont want to exceed 15. Even 15 is pushing it. I had my driveshaft at 15 after the lift, and desided to get a Tom Woods one piece drive shaft. Had a bad vibe.

 

Welded it up and went with ten- Deffinately need a longer rear driveshaft. I am amazed at how high the all-pro 5" lift with 36 iroks put the truck up there! Certainly top heavy.

 

When you're able,put up some pics.
