Quoted from PinballGalore:Next im not sure regarding Part number for this carriage bolt there are so many sizes and lengths. Which would be the correct
One for front of cabinet? Since the other three don’t look great either I’ll just replace all Four if I’m Putting a new Order together.
those holes are for the mounts for the lockbar that B/W offered on later WPC games. i just checked mine and i think the carriage bolts in those slots are slightly longer than the ones that hold on the coin door, but that would only be important if you were going to install the lockbar and related brackets. you should be able to fill it with these (though you can look for similar elsewhere):

the originals likely didn't have any raised lettering on top but it's now pretty much impossible to get any new that don't; the only way to get around that is to grind them off and repaint which IMO isn't worth it.
Quoted from PinballGalore:And just one more for today - Where can I find the metal piece on the other side (right) of the blue rubber? Is there a part Number?
oddly enough, i was reading backwards through this thread last night (starting on this page) looking for some other information and i came across this subject. apparently it's long since been discontinued, of course, but someone is making them. the big drawback for some is that it's without threads so you'll need to have a tap & die set to put the proper threads in yourself. i'm feeling too lazy to skim back at the moment, but the relevant posts are likely within the last 200 or so.
