Thank you.
Every page over at fordification lists the source of the info. The VIN decoding pages specifically state that the info comes from the Ford Master Parts Catalog. The only page there that doesn't come from the MPC is the production numbers. Since those aren't available to the general public except through a Marti Report, they use the same source that you've used yourself on numerous occasions...the Standard Catalog of Ford Trucks and yes, the Ford Pickup Red Book. (But a disclaimer at the top of that page also states that the numbers posted can't be relied upon and are therefore just there as a general estimate.)
It's my impression that while YOU might think of them as a "rival", and do your best to cast dispersions upon the accuracy of their data with sarcasm, they're there just to help others...and 99.999% of the time, their info is correct. A large percentage of your posts, on the other hand, are literally dripping with sarcasm and egoism. Get over yourself and grow up!
