Attached pic looks straight up from floor. You can see the floor plug for original MC access. I don't know why they couldn't make the bracket to fit the dual MC in its original location under the floor access plug!!
No worries, my floorboards aren't concours perfect so I've got a 3 inch metal cutting hole saw on the way, will simply have two floor plugs instead of one. MC lid can easily be removed from underneath truck, then fluid poured in from top.
For trans clearance remember it has to be moved
back toward the brake lines before it's lifted out.
