Trans bolts access panel.

I do this with my four Speed hump. that's why I tell people to just bolt it down or screw it down and not to weld it. Pop it off and you can get the two top transmission bolts and slide it out easy.
I want a 4 speed to put in my dart! I wish now i would have kept that extra 3 speed i had with my barracuda. My dumbass let it go with the car.
