The top motor mount (#8 in the link) for the CB350's is no longer available. I'd like to get the motor mount powdercoated and need to drill out the bushing before i get it coated. Can I make a similar bushing out of delrin or some other similar material? For reference, this is just a standard old bushing which is just rubber between two metal sleeves.
