70 GSX Stage 1 Original Non AC Radiator Info Needed

Don't know if this helps or not but my 70 Skylark with A/C had the original radiator in it when I got it about eighteen months ago. The metal tag has IA and CF and SJ stamped into it with a 3 lower down on the tag. The reason I say had is because I had to replace it after the tanks developed pin holes in them. Radiator shop said it would be a waste to try to repair it. I did keep the tag though.

Thanks Larry

I believe they did share the same unit.
