My observations: First issue factory '69 thru early '72 caps were chrome over brass construction. Notoriously weak, they crack and dent very easily. A switch was made sometime in '72 to stronger stainless. Some assembly plants kept installing chrome caps till supply exhausted. Now, if you went to the GM parts dept. back in '69, '70 ,'71, you would get chrome over brass. If you went to the GM parts department in the mid 70's, chances you would get them in stainless steel ( the method of construction till '75), unless they had the older unsold chrome caps laying around. This comes to a whole other topic of NOS parts made in the early 70's vs. NOS parts made in the '70's or 80's.
