The only brackets called out in the spec are rear end mounting brackets. The spec also says that all "structural" welding in the drivers compartment needs to be tig welded. Interpret it how you want but it doesn't say that small brackets and tabs for non structural items like dash mounting or chute lever mounting etc have to be moly and tig welded. There's no doubt in my mind that some will insist that every bracket and tab for even the smallest item needs to be moly but there's also no doubt in my mind that there's plenty of cars out there with mild steel tabs.
