Thanks, it is encouraging that they are the same from 64-7. The two trucks I am working on are actually 65 and 70, so I am not really concerned with the 63, I just thought they might be the same as 64-66 so I included that year.
I may have to just take both apart and compare side by side.

Thanks again,
Jason
