I thought I saw one of the trucks (the Suburban?) with what appears to be taillights from an early/mid-sixties fleetside pick-up. Looks like they built the Brazilian trucks with over-runs of parts from earlier years. Your best best is to get print catalogs from as many suppliers as you can. And that would include catalogs for parts from earlier years of trucks too. That way you can compare the parts on your trucks with the pictures in the catalogs. I strongly suggest catalogs from LMC Truck. They have alot of really clear line drawings of most of their parts which, in many cases, appear to be from the original factory assembly manuals. Also, many of the suppliers have good photos of the parts they carry on their websites. So if you think you have found the correct part in a print catalog, you can then go online and see if there's a better photo on the website.
