* Classic Chevy Parts Suppliers: Companies specializing in classic Chevy parts are your best bet. They often have reproduction frames or used frames in varying conditions. Search online for "1970 Chevy El Camino frame" to find these suppliers. Expect to pay a premium.
* Junkyards and Salvage Yards: This is a more budget-friendly option, but requires more legwork and luck. Check local junkyards and salvage yards, both online and in person. You might need to call around to see if they have any El Caminos, and the frame's condition will vary greatly.
* Online Classifieds (eBay, Craigslist, etc.): These sites can be good for finding both new and used frames, but be sure to carefully examine descriptions and photos for any damage or rust. Be wary of scams.
* Specialty Forums and Online Communities: Join online forums and communities dedicated to classic Chevrolets or El Caminos. Members often know of parts sources or have frames for sale themselves.
* Restoration Shops: While they may not sell frames directly, restoration shops often have contacts and can point you in the right direction or possibly source one for you (at a cost).
Important Considerations:
* Condition: Assess the condition carefully. A rusty or damaged frame is more trouble than it's worth. A completely restored frame will be expensive.
* Shipping Costs: Frames are heavy and shipping can be extremely costly. Factor this into your budget.
* Frame Number Matching: If you are pursuing a concours restoration or are concerned about originality, ensure the frame matches the car's VIN if possible.
Starting your search online with specific keywords like "1970 Chevy El Camino frame," "1970 El Camino chassis," or "1970 El Camino replacement frame" will give you the best results. Be prepared to invest time and potentially a significant amount of money to find a suitable frame.
