Probably ss fasteners if only just to bug David B. who will point out the electrolysis problem between stainless and aluminum :)

Won't be a problem at all, large amount of aluminum, small amount of stainless. If on the other hand I had a stainless bumper and for some reason used aluminum bolts.... then the bolts would be gone in a while.

As to worrying about aluminum bolted onto the vanagon frame, well I think you are too late in that worry. Happens all over the van, including your alloy wheels :)

cheers
