I've got an original new ford v8 cat assembly I bought for my 94 bird a few years back.
A friend of mine has a 97 cougar that needs new cats. The part numbers from ford say they are different. Does anybody know if this will fit and or any mods it may need?
1997 Mark 8 LSC
1996 Thunderbird lx 4.6
1994 Thunderbird lx 4.6
It will fit and bolt up with no mods. The difference has to do with the 3rd cat and resonator area. Ford changed it for 97, I want to say they eliminated the resonator, but the mounting locations and flanges are the same, so you can bolt either pipe to either year.
