FYI, they're manufactured by AMP researchbut marketed by WestinAutomotive and Bestop. I've been looking at these but there are two different part numbers that are being claimed to fit the 3rd Gen Dakota. Various sellers are listing both the Westin P/N 10-0020 and the 10-0025 as fitting the Dakota but they're different sizes. The AMP p/n recommended for the Dakota is 74502-01 but I can't find an AMP/Westin P/N cross-reference. For those that have purchased, which one is correct?
