    Can the pittman (output) shaft seal be replaced without disassembling the box? Also does anyone see a downside of drilling a small hole in the side cover where the adjusting screw is to vent the pressure from the box?
  2. A better solution to venting the box is to drill the bolt that goes through into the cavity, it's the one on the inside of the box. I drilled mine almost the length of the bolt and then in from one of the flats on the bolt head. It's a good solution and relieves pressure that builds up from heat from the headers, etc.

    I found the seal part numbers from the archives from the posts by Digger Dave and yourself on this thread:
