I remember there was a concrete company near me where I grew up In Miami, FL, that used orange Paystars to haul concrete blocks. Saw one of them dump his entire load off the side of his truck when he took a right off of US 1/South Dixie Highway onto Sunset Drive/SW 72 St. What a mess!
The Paystar is a construction truck, so you'll see a lot of them as dumps, mixers, or heavy haul tractors. Search on Hank's Truck Pictures for ideas. There should be thousands!

You can try emailing Daniel ar Plaskit Resin (plaskit_resin@yahoo.ca). He might have some. Or you can check with Dave Natle over at American Induatrial Truck Models (http://www.aitruckmodels.com/).
Good luck.
I thought so, too. It'll be a "rebuild" as I bought the Peerless in 1985. Just have to figure out how to make the rear stringer for the tractor. Shouldn't be that hard.
