‘65 4 Speed Hump Install

I’m not sure as this is a third hand picture, I don’t have direct experience. I’d like to cut as little of the floor as possible. I’m going to try it and if it doesn’t work, I’ll widen the cut.
Exactly. It just makes more sense to cut as little as possible. Just because the factory hacked them all to heck and back, doesn't mean we have to. I rather like the install you shared. Do you have a finished picture?
