Chris, I'm hoping that i'm the fourth person you're waiting on. Apologies for the delayed reply, but I was out of town and totally forgot about getting back to you!
Anyway, I know nothing about coin mechs since I just only bought my first coin door 5 days ago. I took some pictures (see below) and wanted you to confirm that your mechs would fit. I know you can never be sure, but at least we can be reasonably sure before you send them to me.
In my coin door, the mech on the left sayd Happ Controls and the mech on teh right says Asahi Seiko. Does that help you identify them at all??
If you think your mechs will fit, then YES! I'll take a pair of MODIFIED mechs! I've got notification checked, so if you respond that the mechs will fit, I'll send you funds ASAP!!!
