Dave,

Thank you for your reply. The co-owner of the private garage (not the mechanic who recommended finding a used catalytic converter) said the same thing you did: it is illegal to sell a used catalytic converter in CT where I reside. My hope is that prohibition is not nationwide in scope. But there is another practical problem I see in trying to obtain a used catalytic converter aside from being over 20 years old: catalytic converters contain high value metals and have a high salvage value. My concern is (though I have not confirmed this yet) most catalytic converters are immediately scrapped for their value due to their content and are not even available to be sold used. I'm still looking though, and will continue to welcome any suggestions or comments.

Hugh
