Even though I have a $500 deductable (the total cost of replacement is $1,295), I'm going ahead and having the whole thing replaced. Too much "else" could go wrong after I change this or that. That'll teach me to listen to DW who insisted we sit under the shade...O.K., I'll still have to listen to her but I might get a word in now. :-)
