As far as I can tell, these both should fit all '73-'91 Suburbans. #1) "Valley" 4000lbs gross weight, 400 lbs tongue weight, without weight distribution, 9500 lbs gross weight, 1000 lbs tongue weight with weight distribution #2) "Draw-Tite" 5000/500 lbs without, 7500/750 with. Both have the above info clearly marked, neither one has any structural damage that I can see, just paint flaked off and surface rust. Photos available by e-mail. I'll try to keep an eye on this forum for responses, but for quickest results, e-mail me at firstname.lastname@example.org . $50 each, plus shipping.
