When I did the conversion from Auto to 4 speed on my dart sport I dropped the column out comletely. Then I removed the brake pushrod bolt and the master cylinder/brake booster's 4 nuts from the studs coming through the firewall(the studs are part of the pedal assembly). I left the lines hooked up, I just sorta pushed the Master cylinder forward in the engine compartment with the lines still intact. Then I removed a couple mounting bolts under the dash and the whole assembly came right out with a little maneuvering. When the column is out it's definitely a lot easier to do the swap and to see what is holding the assembly in.Just remeber to pull the big bolt out of the brake pedal arm( the one that goes through the brake push rod) assembly first before sliding the master cylinder forward off of it's 4 mounting studs. Hope this helps. :-D
