[Fot] TR6 Rad Fan Extension

[Bill Babcock]

Uhhh. What?? I don't get it. Is this a street car that you want both  
electric and crank driven fans? Most people building race cars use  
the fan extension for a paperweight. If you're using a harmonic  
balancer most of the ones I know of have no provision for mounting a  
fan. It's generally assumed you're either going to run without one  
and just use motion cooling, or you're going to add an electric fan.  
I'm not sure what you're up to.

If you are calling the existing fan pulley a harmonic balancer then  
you need to look again. It's just a pulley.
