I need 4 spacers for spacing my shock mounts from the chassis. They are just simple parts with just an ID, OD and length, and can be done on a lathe. I would happily pay anyone who could make them. They are to fit a 3/8 bolt, so they need to have an ID to allow for a 3/8" bolt, and OD of 3/4" and a length of 1/4". Can anyone here help me?
