5 speed in a Dart. need input!

Here is the cut floor for the floor hump. Shift rods 1-2 and 3-4 go over the trans x-member and Rev goes under the trans x-member. You need that much clearance for the 1-2 and 3-4 rods.

Lay the hump on the tunnel, it basically centers itself close to where it should be. Get a marker and outline the perimeter of the hump on the floor and measure approx. 1.5" inward and mark that area. Start cutting the floor on the 1.5" mark and be careful NOT to cut thru the floor support.
