904 trans - cable vs rod

I've never seen it done but that doesn't mean it can't be done or that someone hasn't spent 1000's of hours and dollars doing it. The question is.....why bother? The stock push button trannies are just as good as their later linkage counterparts if you build them correctly. The benefit you get with the early trans is that you can push start the car with them.....rear pump.....remember? I know, you don't like the ball and trunion U-joint. Well, there are conversion kits available to get rid of those. Check your local driveshaft rebuilder.
