I'm doing the 216 to 261 swap for a '50 Sedan and the 261 did not come with the harmonic balancer. Does the 235 and the 261 use the same harmonic balancer? Does anyone know who sells new or rebuilt balancers for these engines? If I get one out of a junkyard, given that it will be around 45 years old, is it mandatory that I get it rebuilt and how do you tell if one is bad and needs rebuilding? I tried the "Damperdoctor" but he hadn't heard of the 261 engine. He did say he could rebuild a 235 if I sent it to him.

thanks,
Dan
