I like mine but when the explorer diff project is done it'll make it that much harder to pull the driveshaft.  I'll start by making a stud plate for each side of the loop on the inside instead of just bolts and fender washers so I don't have to have extra hands to pull the loop entirely.
 
If geometry still makes the loop too hard to remove w/ the driveshaft it'll end up being a two piece.  Mines made of 1/4" plate so it could probably be lighter too.  That said, it's stout and I wanted that having seen some carnage pics in the past.

My buddy gave me a brand new universal DS loop that the guys renting his house left when they got kicked out. I'll be installing  that shortly. One question I have is placement on the vehicle per sactioning body rules. I know the tunnel /exhaust setup on these cars leads to the belief that the DS wouldn't go far under u-joint failure. While. Believe this is somewhat true under slow speeds (where most u joint failure is lowly to occur) under higher speeds a front u-joint failure would be pretty nasty in comparison to the rear u-joint failing. If I remember correctly NHRA requires DS loop to be no more than 6" rearward of front u-jont. This is surely gong to complicate my efforts to run dual 3" exhaust between my x-member and DS. I'll post some pics as I get it figured out.
