[Spits] Heater Core

[Roger Elliott]

Hi Everyone,

I just found out that the heater core on my Spitfire is leaking.  The 
new ones seem to be a bit pricey even though it appears the price 
includes the housing, at the places it is available.

Has anyone had the core fixed at a radiator shop?  Are all of the heater 
cores interchangeable between Spits and GT6s or just some years?

I have a used heater box from a GT6 (Mark 1 I think) , but I don't know 
what kind of shape the core is in.

Thanks,
Roger Elliott
