[Mgs] MGB Heater Fan 67 BGT

[Mark]

I decided to take a look at the heater fan this morning.  It makes a lot 
of noise and vibrations in the cockpit.  I have a metal squirrel cage 
that turns out to be mostly oval which is my problem.  I have tried to 
straighten it out without much luck.  I can't imagine how it got so out 
of round unless it was pried off a rusted shaft.  Moss lists only a 
plastic fan replacement, any thought on how they work compared to the 
metal fan?

Thanks
