This radiator is a Direct Fit for all 1961-62 Corvette with LS engines with an automatic or manual transmission.

This radiator will provide 40% + cooling over the Stock Copper radiator. It is also epoxy free. It will fit into the stock core support and comes with 2 rows of 1" tubes. This model has a filler neck on the radiator, which eliminates the stock Harrison overflow tank If you opt for the Automatic transmission cooler on this model, it will be in the driver side end tank. Lines will need to be located to that side of the car. Lines for this cooler are 5/16" inverted flare, like you would find on a typical 60's style GM car.
