Rick, Very interesting reading. I'm dealing with a '69 b-body, also,
but mine had a MPB disc conversion done by the former owner.
The aftermarket kits should have all the bugs worked out. The brakes
don't work bad stopping the car, although I don't think the rear
drums are working. I was interested in the steering 'abnormalities'
you stated from mixing the wrong parts.
Although I have paperwork from the former owner showing alignment
being done and a rebuilt steering box from Steer and Gear, the
car handles poorly especially on secondary roads. Any input on this
system, anyone?
