Auto to manual conversion

I would argue that it's better to not permanently put the floor hump on. And I'd also argue that's integrity isn't affected if it's done right.. again I just put my floor hump down there when I got it and drew a line around the edge of it then I knew I could come in from that edge about 1 in and cut out the sheet metal... Then I took that thick sponge one side sticky window seal from home Depot and stuck it around the edge so when I put the hump on it's sealed.. then I put about a dozen self-tapping screws through that all the way around.. then on top of that goes the carpet... I have never had a problem with it... Every time I have taken my engine out I've peeled the carpet back undid those screws with my screw gun was able to reach the top transmission bolts with very little problem..
