OER RADIATOR

I had the same rad #2949066 for my 69 4spd barracuda. THAT is a high $$ rad. Even if the core is puked it's worth $$. I had mine recored and an extra row added. He split the top and bottom tanks and added to it. Top notch, you cant even tell. I'll chk for pics, and yes for 69 the factory used that rad for auto and 4spd. 68 had different part numbers auto vs 4spd.
I'm looking at purchasing the OER Radiator Number MA2246A, from Classic Industries, for my 69 Swinger 340, 4 speed. This radiator is a 3 row for an automatic. The stick 3 row and 4 row radiators have been back ordered for a long time.

My original radiator number is 2949066, which I believe is a 2 row, for a stick or an automatic. Any thoughts on whether I would be making a mistake on purchasing this automatic radiator. I don't know why they even have a different radiator for a stick and an automatic. Does it make a difference in cooling?

Thank you in advance for any comments.
