Thanks for the replys people.I have meausered it to be exactly 1/8 of inch instead of the 1/4 I originally posted.Keith is correct,the engine was balanced and they added a nice size chunk of weight to the aftermarket flex plate that I am using.I am currently waiting on my pulleys and waterpump to come in that I ordered to see how everything alighns up.From there I should know if any modifications need to be made to the sleeve.I was worried I may have had the wrong balancer.This is the first 428 I have messed with and also the first romac balancer. Thanks for the help
