I could have ordered Marlin's R10 adapter when I did my dual cases. I just ordered up a regular adapter since I already had a used All-Pro crossmember. I don't really see the benefit of clocking 10 degrees. I know some of the Inchworm stuff is clockable above 10 degrees and that might start making a difference. But 10 degrees doesn't seem like alot of clearance. I've only been hung on my belly a couple of times. I serious doubt that extra inch would have helped me.

 

Maybe with a stock height t-case and especially with the under-case crossmember, then the front drive portion of the t-case is not hanging down all that much lower. But for me, the 10 degree clocked case will let me get that lowest hanging bit up iside the frame rails (drivetrain lifted 2"):

Since that is the lowest hanging bit under my truck, if I do get hung up underneath, it'll be on the front driveshaft/CV joint and those are expensive to replace if damaged!

I'll be covering the rear shifter hole and running the rear shifter up to the front hole with a triple stick setup.
