67-72 gauges do not have numbers on the face, but they do utlilize the two different gauges, 60 and 80 lb.
you are right, no BB in Blazers but lots of gauge panels swapped in and out so you may have an 80 where a 60 would have been stock.

That's true with all the swapping on these things over the last 40 years.

With that said then the original posters best bet is to do what I did, and temporarily hook another mechanical gauge up just to see how it reads in comparison.
