It will be a GM P32 chassis and if you can find the GVWR, almost any decent medium duty truck shop should be able to help you source parts.
Workhorse didn't exist prior to 1999, so asking for their parts likely will only confuse the issue.
OBTW, WELCOME to iRV2.com, where we also have a "VINTAGE" forum and perhaps somebody over there can be helpful.
