[TenTec] Two Century 21 problems

[Tom NØJMY]

Right-O, Frank.  When I was in the truck business we used to use a 
similar Loc-Tite product called "Stud and Bearing Mount".  I fixed a lot 
of things, including certain radio things with it.  But only if I never 
wanted it to come apart again.

As one of my mechanics used to say, "that stuff's harder'n Chinese 
arithmetic!"

73,
Tom
