The thing is, I don't have a parts diagram for these Macs. Your parts listing requires that I know a part number for what I would be ordering. I wish that on your site you would put up more pics of the parts if possible. I know the model of the chainsaw and a description of the part, but on some saws the part is missing so I can't even look there for a part number. One item I'm looking around for is a top front handle for a McCulloch Pro Mac 700. I might be able to straighten the one I have now but probably couldn't make it look right. Another thing is, I'm kinda on a budget with these saws and couldn't afford to pay the prices that Wallenberg (website previously suggested) wanted for his items. I found the clutch drum that I wanted for it at a local shop, I guess it's a common item.
