Welding in 4speed hump

When I put my for speeding I put self tapping screws with some sealer around it. Mind you my cars are race car so I don't have carpet. But now when I want to take the gearbox out I just pulled those self tapping screws and I can sit in the driver's seat and take the two top bolts off the gearbox and pull the tranny like super fast and easy. I think while doing it makes it to permanent, there's a lot of advantages to be able to take it off when you want to.
