Oklahoma Dept. of Transportation, ODOT, sells county maps that show Sections, Townships & Ranges for a nominal amount. Some counties are on 2 maps. I bought the whole set for all 77 of Oklahoma counties a few years and have found them invaluable.
Try this website and if you have problems accessing it let me know. It's the McClain County maps and you can enlarge and print them. http://www.odot.org/maps/county/map_co_44-mcclain.pdf
