[71 super]

There are a few inaccuracies in the above descriptions. As per Gm :
Cheyenne- lower wide chrome -woodgrain w/tailgate band, interior dome light switch, cargo light, chrome front bumper, chromed hub caps, full foam seat, cigar lighter and deluxe trim interior, bright window moldings-all, chrome front bumper, wood grained door panel inserts (72), headliner, Cheyenne name plate Z84 optio same as Custom Sport truck. NO wood grain on dash or glove box upper molding available at additional cost as were radios and any trans any engine combo above 307/250 w/3 speed.
Cheyenne super option YE9: Chrome front bumper, full wheel covers, upper and lower chrome trim, wood grained dash and glovebox trim with emblem(super), special seat trim- houndstooth bench seat only- buckets recieve vinyl trim only, special name plates for fenders. All other options available at extra cost- so you could have a 250 6 with 3 speed and cheyenne super trim, radio delete truck with rear step bumper (which was a higher cost option).
My 71 is a factory super as is my 72 - the options on both trucks are very different in some respects- the 71 was ordered to pull with and came originally with below eyeline mirrors and the step bumper. The 4x4 has a manual throttle and did not have the chrome transmission shifter- there is some question if supers came with a chrome transmission shifter, but it definately came with chromed transfer case shifter. Hope this helps answer you questions.
