Guys no offense on this. There are allot of goods Ideas on here. The Mcleod guys have great intentions. However they don't have any of these out yet and to make a claim that it will fit with no tunnel mods after what I have seen of it will be a tall order.
That being said. If you go to a Stock TKO you will eliminate the center of your Torsion bar crossmember. The shifter will be on center line not offset like a factory Dart.
The Best price on a TKO is $2095 for a stock TKO500. The Ad you saw for 1700 plus I can assure you unless its used you wont get it for that.
You can also use a 3650 or our lower cost T45 if you don't mind modifying.
