i know for fact that 3.40 was used in at least 76, i scrapped a 3.40 12 bolt from under a 76 gmc pickup last fall, by accident,. check under 76 GMC's anyways. if i can find the SPID lable i can give you the RPO code to look for, i believe it's GU5, all you have to do is look in glovebox for the label and look in the codes lists on it, if nothing is listed then its probably 2.76 or 3.07, this 76 was 350/th350 not a heavy half, just a std half ton with std width rotors and 2" wide rear shoes

good luck
