Ok so I have been doing some checking for this spacer and have been told that the 742 case because it uses shims dose not require a spacer, can this be correct? I even phone a diff only shop on the mainland? I looked on Dr Diff site and dont see one available either just a crush sleeve for the 489?

if you cannot find the shims locally -- you can get them from Ratech Manufacturing --- [email protected] --- pinion bearing preload shim pack 742 case # 1107 ($12.00 US ) and pinion depth shim pack 742 case # 1108 ( $20.00 US ) or Summit Racing carries Ratech stuff as well.
