Had the same issue when i did this about decade ago....their jig they do the G body 9"rear end is wrong and has been well before i purchased mine.
Fix was an angled spacer like the others did
Great idea doing the chamfers for better rtv sealing.....I didnt do any of that.....just pressed the studs in and was perhaps a bit more liberal with the right stuff application?
For the axle seal.....just threw another duralast seal in....and it has held up this time around
Good explanation
I’m not the type to use a weather station before I take the car out…. But do note the ambient temp in my log book if a change is made
2-3 psi is about all I see with 20 - 30 degrees temp swings
( dry climate)
That boost gauge starts lyin
