If you have a standard tranny, then get what fits. Three hoses and a bleeder to the pastic filler tank. It works or it don't.

If you've got an automatic with the tanny/rad connection, then there is more potential damage with a failure and/or poor quality fittings/ construction.

CFS: used to make a 3 row rad that IPD sold...so more (I've got then running in 2
Volvos for years) has some 2 row "until stock runs out"

Nissens. If you can find the all metal


However

If you've got the original Brass/Metal, then if it ain't in bad condition, just clean it out, you can take it to a radiator shop that will "hot flush" it or "rod" it. as long as the mid metal part is not rusted out.

You can even have it re-cored, at the right shop. Replacing the middle finned part...keeping the top/bottom

The killer was the later model 240s that came with Plastic/alum rads...pretty much not fixable.
