My 46 half ton is extensivly modified, 261, T-5 trans, 66 half ton rear and still using original master cyl, pedals etc. The trick is to keep the original bellhousing with it's mount for pedals etc, you'll need an adaptor between bell and new trans available from Buffalo Ent (banner ad runs on this home page). You can also use the EARLY 50s truck bellhousing but then you'll need to go to a totally different pedal and master cyl set up or fab a new mount for your master cyl etc.
