Can someone please send me a link to a coin door lock that specifically fits a Galaga upright cabinet? The one I bought off amazon isn't long enough to get behind this protrusion on the frame (see pic). Thanks!
Try bending the part of the lock that makes contact with the protrusion (I can't think of the name) with a pair of pliers. If not you can buy cam locks at home depot for about $4 or $5 each. This picture is from a gorf cabinet, which should have the same coin door as a midway galaga cabinet.
My Galaga coin door doesn't seem to have that metal tab, but just bend the lock like SNESNESCUBE64 is saying... pics of my coin door for reference. I actually had to bend my tab in the reverse direction.
