Um, yes he does.
I've reused the stock skid plates on most of the rigs we've done the Clayton's stuff on. Either drill/tap two holes in the crossmember or just a couple of litle stitch welds.
Nick (outlawjeeper) has a Warn t-case skid on his rig /w the Clayton's setup that fit REALLY nicely. I'll try and get a pic of it up.
