What pulleys or radiator 68 dart

I had a 69 Barracuda notchback years ago, originally a 318 car. I put a 78 360 in it with all of the 69 front end parts and pulleys, AC,PS and everything aligned perfectly. I remarked the balancer and used a 69 down front cover. Chrysler made the pulley mounting face of the balancers the same thickness on the cast and steel crank balancers. Big block also.
