RE: aluminum radiator

Cody,

I have a brand new 'all copper' radiator sitting on the shelf. It was 
bought from somewhere in the States who described as a 5ktq unit, the 
shipped to New Zealand a few years ago for a 200tq project that was 
abandoned. It looked identical (just newer) than the part that came out.

If I recall about US$160 was paid for it. I could always ship it backl ;)
