Roll pan for avalanche

I'm a little confused as to what metal rollpan fits on a 2005 avalanche, no cladding.
Is it the same as a silverado or tahoe, what?
I wouldn't mind bolt on, but i think i'd like a welded style better, a little smoother and I don't think it'll crack due to the solid body the av has.

thanks in advance,

sir Michaels has one that is listed specifically for the no cladding avalanche: Bolt-on: 2072101

ok thanks, getting it ordered
