Will an 86 Suburban Class V hitch fit a '72 C10?

[LILREDGMC]

After I got the Longhorn and saw the flex in the step bumper/modified hitch, I went in search of the right setup. Could have taken it from my GMC which has had one since 81, but checked around and Carquest had a special on. Valley hitch, for about $105. Used one of the existing frame holes as a locator and drilled the other two per rail. Just needed to get a drop coupler to keep the trailier near level during towing. I can get you the Carquest or Valley # if you need it. Since none of your options are local, why not spy a Suburban locally on a lot or your neighbors, and measure the rails of it and your own rig. Hope it helps a bit.
