I agree with the rest of these guys Alvin, the retailer doesn't make the patch panels, and the fit will vary with every truck - I can't imagine expecting to use sheet matel patch panels without having to do some metal working as the fit and finish on these ol rigs was crummy right from the factory, they were the cheapest of consumer goods, not precision instruments
I'd suggest that if you don't think the panel is useable, send it back for a refund and try someone/something else, Classic Parts can't "fix" the part
