A question for the Morgan owners with the 4 speed gearboxes.
Has anyone fitted a remote overdrive unit such as is offered by Overdrive Spares in Rugby (and others)?
It may be an alternative to fitting a Ford T9 5 speed box and possibly not much more expensive than having a T9 box properly rebuilt and easy to remove if originality is an issue.
It may be a very tight fit even under a modified transmission tunnel.
