bigedpa - I'm not "Utah" but I 'll help out. Here's what you need
Classic Industries ME168. These fit 1/2 tons 1936-52 and 1947-52 3/4 & 1 Ton trucks with Huck brakes. Shows they're in stock.

Edit - Utah got back before I could hit the post button - LOL! His linked part is the same as the one I showed, but about $4 more expensive, not counting shipping costs of course.
