I like the idea and would spring for the difference in material costs. As for the welding aspect? The high carbon T-309E is the "stainless to mild steel" alloy in wire or stick and I never seen a rocker rust out at the welds so it's a very doable endeavor. I'm a retired certified welder, it was my job for 40 years to know these things...Aluminum? Now there's a different breed of cat. Nobody's come up with the weld process for aluminum to steel, "yet." As far as those Fords go, the whole fastening process of panel to panel and body to frame has changed completely. No welds involved and are fastened with high tech rivets that bond the aluminum when they are shot into place by mainly robots. I was fortunate enough to work for Ford at the Claycomo truck plant installing some of the various conveyor systems through the years...That's why I drive Old Chevy's!
