I cut some patterns if anyone is interested. PM me an address.
You may want to cut your own, I noticed that the outside edge varies from cart to cart, slightly. Probably a little warp as it was being released from the mold. Trace the pattern to poster board (Soda boxes are good) cut it out and test fit. If you could find a short piano hinge, it would work good. They internally mount and they make short ones for some cabinets. You would attach it with rivets and then could conceal them with a veneer strip or...? The latch is the thing I'm not sure of. I would like stereo cabinet magnets, but I bounce too much for those. Auto parts probably has something for that. Or maybe a tool box lock?
I dunno....good luck!
