Re: 84 Tbird project

I replaced the Mac H pipe this weekend because it wouldn't seal at the headers because the s aren't right. The holes for the studs are too narrow so you have to grind the holes out to get them to bolt on. But even then it still leaks so I got a Jegs H pipe, which is similar to a BBK and put it on. It didn't wanna line up at first, but I kept working with it and got it to bolt up and no leaks!
I tapped the smog pump tube and plugged it with a 3/8 pipe plug.
I can say that it will work or at least part of it. The shifter bezel from an 87-93 auto is two pieces the plastic part that snaps on the console and a rubber bezel seal. I decided to try using the Mustang bezel seal with the Thunderbird bezel so I ordered a new bezel seal from LMR. I just took the bezel off and sat the Mustang bezel seal on the shifter and put the Thunderbird bezel back on. It did a pretty good job of filling the gap between the shifter and the Thunderbird bezel so I'm gonna call it good.
I also installed my Pioneer speakers. They're a huge improvement over the 35 year old factory speakers!
