Thank you for inquiring about ETL Parts.   We restore, race, and hot rod DSMs just like you.  Our large collection of parts has accumulated and this website is helping the organize of the inventory.   We love DSMs so much, that we decided to share the entire click link catalog of exploded view diagrams on our website.  Some of our parts are new, some are use, and some are restored;  it really depends on the condition, ware, type of part, and other factors.  This is why we have the Color Coded Diagram Key.   We hope you enjoy our customer service and our extensive parts catalog.
