John, Can you take a look at your Red 4 speed Stage 1 car (if it still has the original radiator) to see if it has a trans cooler with plugs or no trans cooler? What are the codes on the tag/RH tank? Is the SJ radiator with the CF tank (with trans cooler) correct for a non air Stage 1 with a 4 speed? If so, is Clark's radiator correct for a non Stage 4 speed?
It has the CF tank. I need to look closer at the plugs and see if there is a cooler under them. Or, do plugs indicate that there is a cooler there?
I have a fully restored SJ rad with a new core, correct tags, CF and IA tanks 500.00 invested so its that plus shipping if anyone still needs one. Would trade for a 72 CE in like condition or make an allowance depending on your radiators condition.
I have a 3 core Harrison Rad Available, Tank Codes CF and IA, good shape, will ship (your $) Winnipeg, Manitoba, Canada
