I've got some sloppy column play, and I believe it may have something to do with my isolator coupler. Is there any way to replace this and not have to spend $80? I know Bouchillon has them (http://www.bouchillonperformance.com/BPE2119.asp ) Would there be a market for these if they were solid pieces i.e. CNC machined? I know all '73's have them, correct? Would it give a firmer feel to the steering column?

Thanks!
Paul
