Got my '48 216 running - sounds sweet! But... clutch does not dis-engage enough to change gears, even after adjusting to the limit. I have another clutch, but my question is, and I am guessing I know the answer, can you change the clutch without removing the engine? The bellhousing rests on the rear cross member, so it would have to be removed, which leaves the front mount! Seems to me I might as well remove the whole shootin match and do it outside the truck!
