383 Body manifolds in an A?

B-body manifolds usually require shortening the outer sleeve on the steering column up to the firewall, BUT they also don't quite fit properly with the z-bar. We solved this by moving the z-bar rearward as far as it could go. We did have to massage the floor, but this allowed us to use the single ball-stud hole on the 440 bellhousing (1969 bell for the 143-tooth flywheel). It was a little easier with the 383 bell for the 130-tooth flywheel as that one had two ball-stud holes to bolt a bracket to. You also have to shorten the pedal rod and fork rod, but this makes a more stable arrangement. Try to retain the 1:1 lever of the bell crank (z-bar).
