Good news eric.

Worth the price eh? 

Btw, for mostly useless info. The Vw iltis front heater core ( iltis was a light military jeep like vehicle made by Vw, and used by us Canadians among others) is the same as the rear heater core on van.

I bought a lot of them, with other stuff in lot, at govt auction decades ago. I gave away most, used one, maybe I still have one.

But just in case, that’s the cross reference
