For what it is worth, on my 2006 Windsor, it is a continuing issue. I think over time everyone of those plastic spools will break. Has anyone found a better spool that could be used, like metal or better plastic, that could be drilled or modified to use. The other issue with us is the fold if you are not careful. Does the MCD have this issue. Lastly, WindsorBill, do you recall the online store where you found the spools?
