Are you trying to use the balancer for the 54 or the 59? The 59 has a much larger diameter balancer, and it might not work well with the 54 engine mount. You're also going to find that the water pump on the 59 engine sits too low on the 54 radiator to work well, the pump shaft is too long, and the pump must be modified before the fan will clear the radiator. There's an adapter plate made to allow you to use the 54 balancer and water pump on the 59 engine and get everything aligned properly. Make 3 more forum posts so you will have access to the private message feature of this site and send forum member "Pre-68 Dave" a message, He makes and sells the adapter plates.
