[V8] Heater Core Replacement

[toml99 at todomundo.com]

I was actually surprised that genuineaudiparts.com had the core for  
$90.  Compared to the rear Differential that was a savage $5614.05,  
and the steering wheel that I've already mentioned to Dave for $680  
or whatever.  Hell, Audi wanted $49/each for the sway bar bushings.   
I'll gladly buy the original core for $90, as the only car that's  
needed one is the Black car and the previous owners did the core  
around 190K and they used green coolant....Ha.   Tom
