Center cap help

[zieg85]

Can anyone date these center caps.  They bolt through the backside.

Is the bolt pattern 5X5? If so I would guess 73-77. 72 down was 6 lug on 2wd trucks and van I believe?

72 on down was 6 lug if it was 4 wheel drum brakes.  If you had disc up front it was 5 on 5 just like 73 on up.  I know it is early to mid 70's, just don't know when they went to the bolt on from the outside.

From the trucks I have messed with, I have only seen those on a 76 and under truck/van.  Had a set floating around the farm from a 76 G20.  I like them better my self, cleaner smoother look.

Thanks for the reply.  Merry Christmas

Those are exactly what came factory on my 77 with the rally wheels. I havent seen many others with the same color center

Thanks so it would be safe to say 73-77?  I only have 3.
