This is a vintage YL585AV Mallory dual point distributor and copies of the factory installation and key degree instructions.  It was used on both small block and big block Chevy V8 engines.  It has a new condenser, a new point set and a new rotor. It uses a crab style distributor cap (not included).  See my eBay Store for more NOS Mallory parts and distributors.   We charge actual shipping, are glad to combine shipping or your welcome to pick them up at our shop.  Thanks!
