About to rebuild the steering box (BN7), after discovering the leaking seal. Only problem is we can't seem to get the darn thing out of the car. Have everything disconnected from both ends, but can't get it to come through the grille. The steering column is hitting the bottom of the float chamber of the back carburetor, so we can't get the steering box high enough to come out the front. The manual says to remove the 2 plates around the steering columns at the scuttle. The interior plate was no problem, but getting at the bottom two screws on the engine side plate is next to impossible (They've been painted over, making it hard to torque in a very tight space. If we were able to get those screw out, that panel can only drop about 1/4". Yet the steering box needs to come up about 2" clear the opening. Do you have to remove the carburetors to give you the needed clearance for the column?
