I have a 21mm rear bar from a 3rd gen that has been converted into an adjustable bar. It has brand new Energy Suspension bushings and bushing cradles. Check a pic out here;

I can't use it on my CMC car, so I'd like to trade it for a stock 3rd gen 19mm or 21mm rear bar in similar condition. If no-one has something to trade, I'll sell it outright if someone wants it.
IM or email me if you have something and we can work out the details.
Thanks,
Jeff
