Nice Alan! I have a friend in the Walnut Creek area, I'm sure we'll cross paths before long.
Understood on the install. I am leaning towards a quick change rear end center section (Winters SR3620) as the ring and pinion do seem toast. Luckily I have a friend with a press for the carrier bearings should I go that route.
I got the car up on the stands and ran it today - Two videos attached of the truck running and the oil out of the rear end, I think it's safe to say I found the source of the noise.
