Just a sanity check here.

Maybe not totally obvious I guess, but you can use a bone stock console shifter with a reverse manual valve body. Replacement gates are available and preserve the original look.
Dig that, and maybe I screwed up. I saved EVERYTHING, posted it up twice, but I may keep it. Not loving the Cable gimmick, just wanted a faster shifter, w/ positive locks.. and when my car jumped into reverse, 2x, and could have damaged the neighbors, Or WORSE, killed someone (especially a Child) , in my case, nothing did happen (THANK GOD!!!!!!!) could have ripped the door off too. Ever have a Lil Duster w/ 4:10s with a nice lil 340 pop in reverse? You start moving, FAST! My old Camo D-200 4 Door was at a High Idle, 4:30s, 318 built for all bottom end torque jumped into first, bout killed my old neighbor... we were both under the hood.
