I was just on kevinstang site figuring out the year of this, I believe it's a 74 from what I gathered.
Was never my intention not to give credit if kevinstang is the original author. I will change the info. I took the info from http://www.maliburacing.com/ford_9_inch/ford_nine_inch.htm and gave credit on the greaseralley site at the bottom of the page. Thanks for bringing this to my attention.

I didn't mean to criticize you, rather the site that was linked. It is the one that is copying Kevinstang's stuff. I meant it more as a point of information, so someone could go to the original site which I think has more, and better information as well.
