I don't know that it gets much simpler than this, go easy on me though I am no machinist! Basically it's a stainless steel bushing...
The part I need is:
I need them made out of 440C stainless, if you do heat treating I need them heat treated as well. If not, I can send them to my normal heat treater.
Quantity would depend on cost, I'd guess 200-500 ish... Once I have an idea how much it's gonna cost, I'll know how many I want.
Thanks ahead of time
