Hi Jim,
If it is copper / brass, any competent radiator shop can repair it.
If it is aluminum alloy its a little tricky depending on where it is leaking.
The tanks can be welded.
Sometimes the core can be repaired with an epoxy depending on the extent of the damage.
If you choose to go new, we have both types available.
Copper / brass, @ 345.00 RBP
Aluminum alloy, @ 425.00 RBP
I may still be able to get one in the crate with chassis #875 if you are ready to buy, to save you shipping to the USA.
Merry Christmas,
Scott
