Videos for Rebuilding a Ford 8N Tractor

A friend of mine recently acquired a Ford 8N tractor, and has decided to rebuild the entire tractor, including the engine, piece by piece.  He said he had purchased some videos online that show him in great detail what he needs to do.  He bought two videos for $25 each. 

This is not some highly produced slick video by a big multi-media company, but rather a "garage video" made by J & D Productions, three guys who have developed great expertise in a particular area, and willing to share their knowledge.  For the purchaser of these videos, it is well worth the $25 to acquire this expertise or even a piece of it. 

J & D Productions does not have a Web site.  They market their product through the Yesterday's Tractor Web site, a popular meeting place where people gather to talk about and learn about old tractors.   Here's a list of Engine Rebuild Videos - they are at the top of the list.  One of the beautiful things about the J & D's business model is that this video can live forever.  The work is done.  It can now continue to generate income for them.  Old Ford tractors will never change!
