Need Harrison radiator id help

[chads454Ls6]

Hey Guys,

I purchased this radiator that has been redone. it has an IA tank, but the other tank is an XR 4 core. does anyone know what that would have come out of? I have searched everywhere and cannot find it.

IA is a fairly common drivers side tank. Not sure about XR. Does it look like it’s for an A body car? Is it for a manual trans or automatic car?

[chads454Ls6]

Manual trans. Yes, looks like A-body.

Pickup truck had that "square" form which yours has at the top. I believe 69 and 70 pickups used a ia tank on the heavy duty cooling or Ac.

What's the core length?
