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

[BrianStep72]

When talking to my dad today he told me that I could have a Class V hitch (for towing airstream trailers) that came off of a 1986 Chevy Suburban. This is a bolt - on hitch and we were wondering if anybody knows if it will FIT on my '72 C10. He's also giving me the electric brake controller.

I don't mind drilling the holes for mounting, BUT I want to know if it will fit the frame. I've done some searches for Bally hitches on the net and haven't found an interoperability guide. It appears from the Reese Hitch site that '73-84 hitches are same 85-00 hitches are the same (for chevies), BUT what about '72 hitches? what specs are needed? Is it a specific type?

Anybody have an interoperatability guide? OR could anybody go out and measure their '72 hitch width and let me know, SO i can check with the trailer people for an '86 and see if they match?

ideas anybody?
