Default Radiator support question.

I have a 1970 LT-1 conv. 4 spd car that has some rust on the lower portion of the radiator support and I was thinking about getting it repaired or replaced and I am finding several supports listed but am not 100% sure which one I need. The LT-1 cars do not have a overfill tank its just a big *** radiator that vents right to the ground. There are some supports listed for 26.5 inch? some listed for brass radiators?
Can someone direct me to the correct part please. thanks

There were two different copper radiators used on Corvettes in 1970. All big blocks used a copper radiator as did certain small blocks based on options. The copper small block radiator core was 26.5" wide and the big block was 27.5". You'll need the 26.5" wide core support for an LT1.

If your going to buy a new one make sure it is manufactured by Coffman Corvette. They make the best in my opinion.

Cool... I have a yellow 70 LT-1 conv I've owned since the 80's... 79k miles.


The radiator support should be 26.5 inches on center. I've posted the link below and if you use the 15 off code New15, you'll save 15 percent off that price.
