My '51 2 ton truck came with a dump grain box . . . and a broken 2 speed rear end shift selector cover. The lower right +/- 15% of the "Two Speed Axle" cover (from the right edge of the W in LOW to about a 3 o'clock position) is broken off. It looks like the cover is either aluminum or pot metal? I have not seen this item in any of my parts catalogs? Any leads on a replacement?
Thanks y'all, Dennis
