When a new acquisition turns out better than you thought.....

I have a 3.55 chunk that has a clutch type SG in it, I don't know how tight or loose it is, I'll have my axle guy test it unless someone has a suggestion....
I suppose that I could set it in a vise and slip axle shafts in it and try to twist opposite ways with the help of a friend but how much resistance is normal?
My axle guy has some jig he uses to test. He has always been fairly good on pricing too.
I have a bounty of 3.23 chunks.
