Hi - If you can't find the parts, there's a guy in Canada that is/was running a "parts yard". It was all free of charge. All you would pay is for shipping costs. If still in business he may be of some help to you. I had the URL in my Favorites folder but with a couple of moves and a new computer, I've lost it.
Let me search for it and I'll post it here for all unless there's someone else in this forum that has the info.
Regards,
Pat
