Hy rick tool, I'm not positive, but I think that engine has all the correct bosses on it to mount into a 62 truck, you will need to aquire all the necessary brackets of course. As to the legality of the swap, you will have to check with your states D.M.V. or eqivalent. All of todays vehicles have a V.I.N., back in 62 the vehicle could have been registered using it's serial number, or its engine number, you will have to verify which way the 62 was registered. In my jurisdiction we are technically required to notify the Motor Vehicle Branch when we swap engines, although it is rarely actually done, hope that helps.
