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?
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 think you can replace the seal , i believe i have done it. do you have the seal part #? i have it around here somewhere
I found the seal part numbers from the archives from the posts by Digger Dave and yourself on this thread: http://www.jalopyjournal.com/forum/showthread.php?t=85809&highlight=vega+seal "Originally Posted by 36-3window someone posted these numbers on here once: Cr 9818 for the pitman arm shaft seal cr 6130 for the input shaft seal" "Reply by Digger Dave Some more Vega Seal and Bearing Numbers ...

I found the 342517 seals are available at Summit Racing. Thank you for your help!
