Don't know pricing since there seems to be a problem with the website tonight but you might want to check out Austin Hardware
. You are looking for "paddle latches" listed under "Locks, Latches & Catches".
This outfit has hardware for Fire/Rescue/EMS Vehicles, Trailers, Sheet Metal Fabricating, Utility Body, Recreational Vehicles, Marine, Bus and Rail.
This outfit had the "they no longer make these anymore" odd draw latches used on our vintage popup camper (and I mean an exact replacement since I replaced two of the latches) and also had the latches used on the bays of our Eagle coach. The catalog (I still have one) does not have pricing in it, just measurements. Pricing I always got online. They are a source for the Southco hardware.
