I am rebuilding my front end at the moment and was going to purchase kit stlkmopfr for my 67 coronet. I also want a borgeson steering box. 2 questions. Does the kit stlkmopfr have large or small sector pitman arm? Also why is your price on the bogeson power steering box $300 more than any other retailer? Is it the complete conversion kit or just the steering box? I only need the box as i already have power steering. Hopefully another member or pst rep can answer this as i was unable to get a clear answer when i called the sales department.
