Hi all, getting to the end of the show season, so consider it’s time to sort the prop vibrations. Think the consensus of opinion when I first mentioned it, is to get a new prop. We fitted new joints and it helped, but it obviously out of balance as well. Before jumping in and buying a shaft, is there any way of fitting an overdrive or altering the gearing.? Car is mk1. Any more than 50mph seems to be reviving like hell. I know our MGB od makes a huge difference. Any ideas welcome.
