For a pro ratchet make a 40mm box out of about 1.6 mild steel and weld it into the hole that you will cut out of the standard shifter plate (same outside dimensions as the box) then it can sit perfect under standard console and poke through factory slot. I then filed out a slot for the reverse lockout lever but i was then annoyed cause i released you could drill the rivot out, change the lockout lever and re-rivot so that it's positioned to poke out the standard slot. Easy

mine is car so i can rearch the red lever so i can get out of 2nd u have no choice to cut it on mine.. and mines a powerglide.... so id i didnt have the ratchet wat if got u could leave the plastic as normal..
