Rick Freeman was a producer of "aftermarket" parts for the Model A Ford. He relied heavily on South American sources and as such his quality level was not exceptional.
Rick was reported to have association with the JC Whitney bunch.
Rick also published "Model A Shop Manual" book probably to augment parts sales, which was one of the first "How to" books for the Model A after "the day." The date range on these would be late 1960s through the 1980s. The books can still be bought used on Ebay. I would rate the information contained therein as "average" - but at the time of their popularity there was little else.
Rick-Packs would contain "All you needed" to restore a certain component in the Model A, the Distributor, the carburetor, the transmission, the brakes, the rear end(?) And there was some savings over buying the components individually.
In the other thread are narrated some adverse personal experiences of an financial nature with Mr. Freeman. It seems his business practice was not above reproach.
