I bought the Overhaul Manual and the Service Manual for 13 and 10 bucks, respectively, last year on ebay for my 74. The Seller claimed they were new. They looked like they had been sitting on a shelf for 35 years. No black grease marks or finger smudges.

I just took my time and waited for some to come along. I wanted my own hard copies but the search may help you find some .pdf ones.
