Crush sleeve doesn't know or care if it was pre-crushed.
Couldn't get crush sleeve for a while back 1970's, my mentor went next door to the machine shop and had about 100 - 10 thou thick shims made.
We have never bought a sleeve since, - just add a shim and crush the sleeve a bit more.
We were doing a diff a week for a long time .
I've reused so many crush sleeves and just tightened it down "a little more" that I've lost count. Never had a problem. But sho nuff as I recommend it to someone, their chit will tear all to heck and back.
