If you're thinking of a modern type try doing a Google for lots of prospects. If you have a more period correct shell/topper/cap in mind you may have to run a few backroads or watch Ebay/Craigslist for something. May even run across something at a swapmeet or flea market. I had a all aluminum shell on my 59 short step for years and loved it. Reasonably lightweight for install/removal. Still have some pics of it if you'd be interested. Gave it to a friend and last I saw it it was a deer blind set up in the woods.
