Radiator Code
 

Anyone know the right code for a '69 full-size with L72? Is "CS" correct? Thanks for the help!

Yep..if it's TH400 equipped and came with A/C.
The CS code was used on 1969 L-36/390HP & L-72/425HP full size vehicles with TH400 & A/C and also on 1970 LS-4/345HP & LS-5/390HP full size vehicles with TH400 & A/C.Radiator Part #3018035.

If it did not have A/C,then those very same vehicles w/TH400 used radiator part #3018015 and was coded CL.

Rick, I figured you'd know! I need the 4-speed/non-AC variant for this car. Thanks in advance.
