* Online Auto Parts Retailers: Websites like eBay, Amazon, RockAuto, and others specializing in classic car parts are your best bet. Search specifically for "1983 Chevy G20 battery tray" or try variations like "1983 Chevy van G20 battery tray," or even "Chevrolet G20 battery hold down." Be prepared to potentially find used trays, as new ones may be rare or unavailable. Pay close attention to the photos to ensure it's the correct fit.
* Junkyards/Salvage Yards: Local junkyards that specialize in older vehicles are a good source for used parts. Call ahead to see if they have any 1983 Chevy G20 vans in stock. This is often the most economical option, but you'll need to inspect the tray carefully for damage.
* Classic Chevy Parts Suppliers: There are businesses that specialize in parts for classic Chevrolet vehicles. These may be online or brick-and-mortar stores. A web search for "classic Chevy parts" will yield results.
* Chevrolet Dealers (Long Shot): While unlikely, some dealerships might have access to parts diagrams and may be able to help you find a supplier, though obtaining a new tray directly from a dealer is highly improbable after all these years.
Important Considerations:
* Year Variations: While the G20 was produced for many years, there might be slight variations in the battery tray across model years. Double-check the year of your van is precisely 1983 when searching.
* Measurements: If you find a tray online, compare its dimensions to your old tray (or the space where it sits) to ensure it's a proper fit.
* Condition: Used trays might need cleaning, repainting, or even minor repairs.
Starting with online retailers is likely the most efficient approach. Remember to be patient and persistent, as finding this specific part might take some time and effort.
