Re: The 1960 - 1966 Chevrolet & GMC Pickups Factory Correct Restoration Thread
Look up, or google, Julian Date Calendar , it puts the date as March 7th for 066 . Its calendar year . GM used this method on other parts also. As far as how it relates , its always before or close to before the build date of the truck. Do you by chance have the build sheet to this truck ? The master cylinder would be on that sheet also.
