Gents, I know this thread is a bit old, but am new here today and only just started digging in here. I'm getting ready to by a '71 K20 Cheyenne with a tow package: TH350 w/ tranny cooler, helper springs and all stock except for new crate 350. I'm considering hauling my 32' 5th wheel camper with it and would like to see how you guys installed your gooseneck hitches. All resalers of such only list down to '73 for compatibility. I was reading another thread about guys putting goosenecks in c10's which have pinched-down frame rails over the rear axel and shock absorber attachment points on the outside of the frame rails making the installation problematic. Any insight/photos would be enthusiastically received.
