M R S Scraper 18-yard parts?

MRS scraper - Mississippi Road Service built 'er for the Navy, in 1967- Sorry, forgot to snap a pic -
This buggy has 4 rubber wheels. 2 in front. ( Empty Wt. 36k# !! ) 18 yds.

Anyway, are any parts available?

The collar, bolted under the big gooseneck, and holding on to a big 12"? ball, is cracked.

Even worse, the dump linkage is busted...
Looks like somethin bound up and broke the 6-ft. cylinder, which has been fixed,
but the curved track going up the back of pan is bent...
