ToxicWS6

so i dropped the car off at my mech friend to fix my wiggly steering wheel problem that was causing my ignition to mess up and all and he said usually u can just tighten down some bolts, well it ended up being the part the the pins slide into at the tilt wheel part are worn out so i need the new aluminum pieces and the dealer wants like $320 for it, i can get a used column for $350 but its used, what im wondering and hoping is there an aftermarket piece made by some one thats cheaper or something, if not should i go used column or just get the new pieces?, any help or anything will be nice
thanks
