There is no top shifter conversion available for the T-86 that I know of. However, a Ford 3030 full syncro 3 speed will accept a '70's Jeep top shift cover and handle. Jeep used Ford transmissions in the late '70's and cast the top shifter pieces. The overdrive kicker is that Ford didn't make a full syncro 9 bolt cover 3 speed trans. The good news is if you look hard enough you can find an over drive trans mission for a '75-'77 AMC Pacer, Gremlin, or Hornet that used the ford trans and then had a Laycock-Denormanville (nowadays Gearvendor) electric overdrive from England attached to the back. I am running this very setup in my '32 roadster behind a 354 hemi with no problems and very smooth shifts. The trans missions are rare but can be found. since the trans is Ford and the O/D is Gearvendors, parts are easy to get, just hope you never break the output shaft or the adapter, those don't exist any more
