Have a 1979 40 currently with headers. I want to go back to stock. There’s a guy on eBay selling a 1984 exhaust manifold from a 60… is this the same that would have been on my 1979?

If it’s not exactly the same I’ll keep hunting.

From the collector up, they are the same. If you’re building an original exhaust system (not recommended) you will need the ‘splitter’ that attaches to the collector as well, to take the smaller, twin exhaust pipes outside of the frame.

I have a complete 1979 intake/exhaust manifold assembly with 70k original mileage I pulled off a 40 series that has been stored indoors for the last 30 years if you’re interested. You can leave a voicemail at my shop to follow up.😉
