I have the Maier race front end, and I'm not so sure that the stock tank shrouds and radiator cover will fit. The stock tank shrouds have tabs that fit into the stock front piece, the Maier does not have these tabs and the race piece doesn't have the slots for these tabs, but the tabs may fit behind the Maier piece.
Sorry this doesn't help much and I don't have time to try it out to see for you today.
