Yes, it does really matter! To me at least. When I purchased the Primary gasket the package read "made in china and packaged in the USA." This really bugged me and still does. I really look at things I purchas, just me. Have a happy 4th of July my country's birthday!
I would also like to purchase everything from US manufacturers. The point I was trying to make is would you still purchase Harley Davidson motorcycles if you found out that the clutch plates came from China? When I purchase aftermarket parts for my bikes I try to make sure they are American Made.
