I don't currently have the space for a full cabinet, but I've been itching to play TGM. So I got the PCB and a supergun to play it with, but I'd like to replace the components on it. Here are pictures to help make sense of my questions. I bought Sanwa OBSF-30 buttons to replace the current ones. The current ones feel a little gummy and occasionally they double-tap when I don't mean to. When I tried to remove the current ones, I found they have a threaded plastic collar that holds them in place and I cannot get the collars to budge. I tried with a channel lock wrench and only really managed to put some scratches on the collars. Any advice on removing the buttons? Also, I got a Sanwa JLF stick to replace the existing one (I plan on replacing both of them but wanted to go one at a time). There's nothing all that wrong with the existing stick, though if I continue to use it, I'll need to do something about the clover shaped restrictor plate it has. The problem is that the current stick is attached with 4 screws in a 2-inch square, but the plate on the Sanwa JLF has the holes spaced in a 1.5-inch by 3-inch rectangle. Do I need to drill holes into the supergun case or can I get a new plate that matches the case?
