1972 Stock weight breaks

[oldskool]

Here's another place to put out another APB for a '72 or '73 NHRA "Factor Finder" publication, preferably both.

So, who has a copy of one or both these "Factor Finder" publications ?

Anybody know any of the older racers who were racing back in '72 & '73, who might have a copy or know someone else who might ?

Anyone know of any online copy that can be accessed ?

Does anybody reading this have any idea how I could get a look at one, or have someone look at one of these for me ?

HELP !!!
