700R4 requires the driveshaft to be shortened, 200r4 does not need any mods to drive shaft. The 200r4 uses the same yoke as the Muncie 4-speed. Bow Tie Overdrive is the vendor I sourced my upgrade from. The 200r4 can be purchased in different performance levels to suit your needs and BTOs sales and tech staff if excellent. T

It’s been abit, removed the center console and to my surprise the shift indent plate is a 3 speed auto original – Has some surface rust so im thinking it’s the factory shifter with a new console with a new shift indicator. So I am going with a TH350 or TH400
