i found this link while looking for floor mats.... 2003 Ford F-150 Harley-Davidson in Belton TX from Shelley's Auto Sales
seems like a pretty fair buy and all stock (except his interior, looks identicle to mine) he also is missing the build plate. It shows the build number as 99083 on the website under the heading "stock" which means it does have the 8 thread heads. Mine is 9051 and i have 8 thread heads as well so thats a nice security in a way
thought i would let this be known
