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?

the 742 uses shims to set the preload ---- NO crush sleeve/spacer --- as stated in my previous post -.030 - .050 depending on the gear --- ask around as someone may have some shims for a solid spacer used with 9 inch Ford standard pinion -- same shim --- go back and read my posts --you do not need the preload shims to check your pattern --just tighten the yoke enough to take out the slack in the bearings and add some preload -- then load your carrier and check your pattern
you need the shims to set pinion bearing preload when you do your final assembly AFTER you have established the correct gear pattern.
