Seth,
I've done one a few time on my Australian 56 Mainline. In Australia we have the steering box, clutch and gearbox linkages in that same space. I remember removing the entire clutch mechanism undoing one of the engine mounts and jacking the engine for space. I think it took 6-8 hours just to remove and reinstall.
The bendix is at the end of the shaft so it needs to come around the flywheel. Stick with it.
The first removal was because the bendix failed and was in permeant engagement with the flywheel. Luckily we were visiting my inlaws, still three hours drive home but I had a place with tools to fix it.
Cheers
Warren
