Used to be you couldnt. So a guy in australia collected them and sold good used parts off of them. Im unable to locate that website, but I did a quick google search and found this; http://www.justdifferentials.com/index.php?main_page=index&cPath=23_38_131
Bearings are the same as a 69-72 Buick skylark A9 bearing The seals are left and right That is weird??? LEFT 224255 This seems to be like a pinion seal...??? Right 710179 This seal appear to be like the buick seal Not very familiar with the IROC Australian 9 bolt... Just one of those odd ball rears we never really get. I will check availability. Jim
Also need to get two Timken Set9 bearings set since they have to be pressed off the axle to replace the seal. Some info and also a note about an alternate seal here: http://www.thirdgen.org/techboard/transmissions-drivetrain/436632-borg-warner-9-bolt.html
