I have a situation. I have a 261 cu that I had rebuilt and I am putting it in my '52 3100. The engine is longer than the original 216 cu so I have purchased the short water pump. When installing the short water pump my fan blade hits the harmonic balancer. After a little research I found out that I have the double pulley harmonic balancer. I would prefer to keep that balancer until later because I may want to add a/c or power steering someday. But for now I need to find a replacement harmonic balancer.
So, I have have the following questions:
will a 235 balancer fit on a 261? I would like to find a used one and get it rebuilt. Or does a 216 balancer fit on the 261?

Does anyone have balancer that they would like to sale?
Does anyone have any recommendations on where and how to get one rebuilt?

Thanks for any help.
