It's an interesting concept, and I currently have a complete driveline sitting like that in my shop. It certainly is easier then climbing in and out of the rear.
I've had my fill of aluminum flywheels and won't go back to them at all.
I have so much "Aeroquip" that I'd just plumb that all with it. At this point it is sort of a multi-task solution item anyway and it would just go back to being coiled on the wall waiting for the next "remote application".
I'm not sure why others are having difficulty bleeding the clutch line? It is fairly simple to do. I think that there is just likely confusion over exactly which slave cylinder they are using. I always look at how early a build the car was since there apparently is just a changeover to the long thrown cylinder at some point?
In any event, best of luck in your build. Sometimes we all need a little? "If it weren't for bad luck, I'd have no luck at all!"
