Parts Cache
As Geof said, a lot of heavy to ship stuff, but I don't see any parts cars, sheet metal etc. In my opinion parts cars vs strictly parts is way more labor intensive.
If bought, inventoried, identified, priced and labelled(excel spreadsheet) right at the start makes it easier from the get go.
For example a cyl head compared to a hood....I would rather have/sit on cyl head...takes up less shelf space??
Good luck!
