Small Block Radiator

Hello friends,

I have a 1977 small block 1.1 Golf that was imported to America from Germany at some point in the early 80's under diplomatic circumstances. I've purchased the car and have kept it running for the last 6 years or so off parts sourced off German and English Ebay. Unfortunately, the original top fill radiator has bit the dust and cracked from the top cap side down to the bottom. Because the American cars had the inlet and outlet pipes on the opposite sides, I can't run an american top fill radiator without rerouting the coolant lines. So now I'm on a bit of a mission to find a small block top fill radiator, part number: 171 121 253.

Any idea on where to source a replacement would be great. I'm not looking for an OEM rad, but ideally an oe replacement that would allow me to maintain the original hoses, radiator shroud and fan.

Cheers!
