The distance from the rear of the door to the rear of the cab is shorter for the 80". (I'll measure mine tomorrow if I remember:angel:)
From what I've been told, the genuine 80" ones are very hard to find, so most of the ones you find would be the 86/88/107/109"'.
Just to confuse things, there are also different versions of the rear wall .:eek:
Bobslandies knows which is which.:)
