i have seen these same shims in body shops for fender alignment. even going to a suspension alignment shop you should be able to find these shims. the bolt is an easy fix. its metric and even if you had to go to a newer datsun or Nissan they would be the same.
i had a guy give me a whole stack of parts years ago when i was rebuilding my 620. I need to get this stuff cataloged. I'ma datsun freek from years ago. I have a 1967 L521 and a 1976 L620 Pickup.
Is there anyone close to kamloops BC. I have two boxes of brand new 60/70's parts that i would love someone to look at and advise me on. I would love to get this stuff out there to everyone who could use Brand New Parts. NOT USED.
