MacMaster-Carr has rubber isolators used for base mounting small electric motors. If I remember correctly, they had a small stud on each end of the rubber cylinder. About 1/4"-20 size.
Maybe one of them would work. They were used on a Lombard front wrap.
Good call! Took a look at the website and found this page:

Are all 4 the same size? If so, I think I have one or two left on the saw that I can measure off of....
