If you were happy with it's performance when it was new - you should have bought a new one when the storm damaged it - before MFJ got their grubby paws on the company and cheapened it up.
It you was good at fabrication - you probably could have made the replacement parts yourself.
And how did it work great for your mom if there was parts missing.
This whole post is a misnomer.
Throw it away, buy a new one, put it up according to the manufacturers specifications and hope that it works as well as the one you bought years ago.
My theory is sentimental value is always 100 cents on the dollar.
Real world tells me that unless you put up the same exact antenna on the same exact location and had the same exact propagation - nothing ever works the same 100% of the time...
