$40????? This isn't Club4AG where they have endlessly deep pockets. You can replicate this with washers. If you are that hung up on the "spacer" being hardened, just get hard washers. $40, holy shit, for 2 thick washers. I can replicate this for about $3 from my local hardware store and a little bit of grinding.

*this is response to a certain F/S thread

HAHAHAHAHAHA yea your right but alot of people would feel like thwasher part would feel weak and eventualy break but i will be ok with the washer thing. Its just I know someone will come back by saying that its unsafe and blah blah and then get in to a big thing. But I say if hecan do it for less then 40 then im in but as of right now 40.00......may be thebest thing for now.
