Hey guys,I'm no expert when in comes to lift kits or lowering trucks.I'm posting pics of my driveshaft clearence after I lowered the back end.These pics is with the driveshaft pushed full forward into the transmission..Is this clearence ok??

 

As long as you won't bottom out the flange, or pull out (lift) you should be fine, I mean as your rear suspension compresses, it's going up and down in an arc (away from the tranny) I'd say with that your fine.
