Sorry for your troubles--- see that cast in 'circle' to the immediate left of Your thumb??
There is a corresponding 'circle' on the right case side...Purpose, a 'case spreader tool'
When installed, well, spreads the case ( about .015 ) so carrier shims can be installed.

I have actually seen 'gorillas' beat shims in with a hammer !!!
& seen 'flat rate flyers' use a thinner shim rather than use the tool !!!

Sorry to get off on a rant DodgeLad... I am no diff 'guru'
This kinda s*** chaps My backside.

There are Really Superlative Diff builders here, do not waste any more $$$
on cretins !!

Again, Sir, apologies for the rant.
