Just now getting caught up on this thread. My September 72 (73) pig has solid apron vents, bug catcher windows, rear marker with grill/vent, tag lights on either sides, and big backuplights
Things I’ve learned from several different pigs I’ve owned.
77 radiator was different than 73
68 plastic rear window gear is different than 71
77 front seat is different and will not fit in a 73
68,69 had a cool different steering wheel, then went to red center, then to blue center on later pigs.
68/E69 had grill mounted markers and apron mounted blinkers
77 heater box had a vent at top like a late model 40.
Door panels changed a few different times over the years, early pigs had chrome metal window cranks, later pig has black plastic.
Early pigs have black with chrome end caps on the interior grab handles, later pigs have gray.
My 68 and 69 pig had lap belts front and rear, no shoulder belts up front.
68-E72 that Ives owned has had slotted apron vents my sept. 72 had solid.
My 77 had non stamped tailgate with orange 4wheeldrive emblem at bottom lower corner like early tailgates.
Late model pigs has different speedometer (has more mph) also believe has an extra number for mileage?
Late 77 and on had chrome drip rail trim also chrome around windows (like fj60)
Last year for the pig had TOYOTA cut out in grill (super pimp)
All I can think of at the moment. I feel sorry for someone wanting to do a full restoration on a 77

probably worse than owning a late 74/early 75 Fj40.
