Howdy, the instant pic I have in my head of pins stacked up in your shed.........mmmmmmm niiiiice! 
Pinball culture and respect has advanced so much over the years......I'll never forget going to a garage sale back in the mid 90's asking if they had a pinball, to get the reply "what do you want one of those dirty old things for?"
Thanks for your offer to help, I couldn't find anything online showing what the coin chute should look like......I want some pics coz I think I'm gonna have to make one. I have a found someone that has 2 coin mechs to sell that take dimes.
