Im looking at going to a 6 inch strech cab on my 77 fj45 this year. Cant seem to find any tops except for troopys and Im not going that way.Does anyone make a good allweather top that could be extended 6 inches? has anyone has made a fj 45 soft top frame/roll cage that use the top and rear flanges from the oem steel top? If the door mated to oem style flanges and that metal had enough meat to attach the convetable top to via snaps or Velcro, would this keep the water out on a heavy rain day?
