[s-cars] Heater Core - Source for all metal version?

[Peter Dowker]

Hi All.

Very sorry to miss S-fest again this year, but the heap just ain't  
ready for road work. Recent events, including the heater core  
replacement project and the intermittent shut down, continue to plague  
me. I must pay greater homage to the Audi gods....

Does anyone have a parts source for an all-metal version of the heater  
core on the urS4/6 C4 chassis. Impex is back ordered at the moment....

Thanks in advance.
