One more reference to the Z and I'll let it go... Fred, considering the cost of restoration vs. the very low value of these cars...have you considered talking her into replacing it? They are pretty cheap.
Ran across this driver on ebay for the cost of weatherstripping alone... That's about what I paid for my daily driver also...
