Hi anybody know what the threads are for the stock 1962 Buick radiators transmission lines? They are one size too big for the RadiatorExpresses Champion radiator i got. It fit ok, i had to cut off the front of the right lower rubbers metal retainer and cut off one side of the rubber on both sides, but other than that it seems like it will fit fine. if there is no such thing as a brass reducer for my needs, i guess i will have to buy and use a transmission fluid cooler. But i would still love to know the threads on the stock lines so i can match them up. I suppose if nobody knows i will have to take both my old and new radiators to Napa and f around for an hour figuring it out.
just found the part i need, a reducer. Weatherhead p/n 7915. Napa had them for $9 ea. you need two.
