Catalytic converters

Go to a parts site or to a parts store. If the part numbers are the same, then they're interchangeable. But this would be the first time I've heard of that happening with two cars so different in age.

You also have to keep in mind the emission control systems of the two vehicles. If one has California Emissions and the other has Federal Emissions, no. Or if one has Northeastern Emissions and the other doesn't, no. Check the emission control stickers on both vehicles and see if they match. If they do then check for physical fitment between the two vehicles. I doubt you'll get a match, but you never know. A less expensive option is to get a universal converter for your vehicle. But you still need to know what emission control system you have. I put a universal converter on my 2000 Grand Prix 9 years ago and it's been fine. Hope that helps! Jim
