So I know this has been asked a bunch of times but I am thinking of upgrading to a 9" so I am just curious. The rear is an 8.5 in housing that I bought new old stock from a circle track racer back in the early 2000's. Its it great shape but has a little surface rust. I have welded the axel tubes, c-clip eliminators, Moser 33 spine spool and axels, 4.10 Richmond gear, Mark Williams 1350 pinion yoke, LPW cover and bracing with beefed up tubes 0.12" thick, (the ones they come with are pretty thin wall tubing), and aluminum drums. I would be selling with an H&R parts and stuff anti-roll bar with upgraded and braced mounts along with the Wolfe racecraft upper and lower control arms. It also has a custom Mark William 2 magnet collar on the pinion yoke. I have been a 1.33 60' with this rear in a 3250 lbs Malibu, running 5.90@117 in the 1/8. I'm doing a serious motor upgrade this winter and thinking about the rear. Thanks in advance
