This is a required part if you are doing an AOD to T-5 conversion. You will realize it the first time you drive down the road if this part is not in when you have hot air that is blowing in near your legs from the center console. Before you cut any sheet metal when doing a swap buy this part and drill the holes out where this part goes so you don't cut too much away.
Fit great on 95 GT made a better seal than worn out ripped original Quick and easy
I bought this part to replace the old (broken) one. It made a huge difference inside the car. Stopped the road noise and no more exhaust smell inside the car!!!!
