bridge over driveshaft

How high should i make the bridge going over the drive shaft? You know, for clearance...

dosen't any1 know? I'm talkin about the bridge the upper bars from the 4-link attach to...

1/2" higher than the driveshaft laid out.

enough so the driveshaft dosent hit it? i made mine with plenty of clearance. just measure. make sure theres room with the truck all the way aired out
