I'm looking for a catalytic converter for my pickup. Don't know exactly what the problem is with the smog yet but gotta look for a few parts cause these things new are really expensive. It's an 83 so let me know if you have anything on the cheap! I'm assuming anything off a 79-83 should work.
I bought mine from :
http://www.davezoffroadperformance.com/index.html . It was the right one the 1st time. It even has the hole and flange for the temp sensor. Somewhere around $125.00 shipped. New too. Make sure and ask for gaskets though. If he doesn't have the gaskets in stock let me know I've got a part # for ya if you need it. I'd have to go look in my tool box.
