Subframe connectors for a driver/cruiser, necessary to weld to floor?

Pretty easy to see which way is best. Look what the factory did with the frame rails they used. Had they made these cars with full frame rails, they certainly wouldn't have left the center rails hangin in the air, would they? lol I really like what @moparmat2000 did in post #80. That really looks factory.

No, it is not easy to see what's best. Comparing a spot welded, thin wall open box to a thick wall tubular connector is not obvious, if you understand how those are loaded.

As I have said before, unless you're going to do a full finite element analysis, which type is stronger is a wild *** guess. It's a guess for me, and I have structural engineering and materials science education. So whether you admit it or not, you're just guessing. You've got no idea which is actually stronger.
