A ford dealer will sell what they say is the correct thermostat, but it does not close off the internal bypass on the 400 engine.
Another bet might be to find a distributor that sells a Mr Gasket thermostat which also has a correct application for the 400. I got mine from flowkooler, part #333-192, and I had no problems with the ordering or delivery. Jeff's Bronco Graveyard also sells them.
