Dave,
I will try to get you some pictures of everything. I spoke to Madison Truck Equipment in Madison Wisconsin today, and I think,I may be in luck. I gave him serial & model # of all parts, and he seems to think he can help me out. They were very familiar with the older hoists, and seemed interested in digging in to the old manual section to try to find out the information I am looking for. They use to be a big supplier and installer of Heil Hoists. I will let you know.
Thanks
Boz
