Seems like this is perhaps my only option to make something "off the shelf" work. Is this an acceptable way to do things, is there any adverse affects on engine wear? My connecting rods have a diameter of .975, most of the pistons available with the correct diameter and compression height are .927. How is this done? bushing pressed into the connecting rod? What are they typically made of? Can you buy them somewhere or does it have to be done at a machine shop?
