Lifted79CJ7 wroteQT wasn't made that long and will only bolt up to the TH400 with the texas bolt pattern and goofy long, low spline count output shaft. The Dana will require a lift, so I say do what Taz recommended and stick the original 208 back in. You can grab them for cheap and aplenty over at U Wrench It!!

There were at least 2 Quadratracs, which causes confusion. '73 to '79 is the Borg Warner version used with TH400 trans and RH drop. '80/'81 was the NP219 New Process version and LH drop (all '80 to '91 FSJs were LH drop stock)
You'd have to flip the D300 or swap front axle. (If you want a goodly front lift, use a Chev or Dodge D4 front with RH drop and factory SOA with high steer knuckles and http://ottindustries.com arms)
I've been trying to find a Dodge NP208 which will (most likely since it's 23 spline and off a 727) bolt up to the Jeep 727, but it's RH drop so I can use my RH drop J20 axles in my '73 J4000 to replace the tired TH400/QT with part time/Overdrive kit (stretched chain from heavy towing).
