Your website clearly says this will fit a 53 Chevy truck. It does not without an adaptor. Upon calling tech support, the representative I spoke with further told me that Speedway does not have an adaptor. I had to purchase the adaptor from another vendor. The result, I ended up paying over twice the price orgionally quoted.
