It can be done from the bottom.  Not what I would call easy but its doable.  basically just carefully wiggle your hand between the wires as you follow the cable up to the back and unscrew it.  It cmes out easier than it goes in!

Thanks terry, I finally got it.  It is just that it it getting harder to get down on my knees (on the rough concrete) then twist around between the door jamb and the seat ( like a corkscrew) and then twist your arm and your wrist up around all the traffic under there.  But I perservered and got 'er done. 

Now it will be easy to attach the ignition lead, for the RallyPac, to the back of the ignition switch and as a bonus, I was able to reach thru and tighten the nut sleeve on my oh so loose cigarette lighter assy.

The sad part is that I did all this back in '82 without even having to breath hard.  Even then, it was all totally new to me.
 

Boom, 4 bolts and the seat comes out then you can lay comfortably in the floor with your legs in the back seat!  I remember legs in the back seat!!       From when i did this! Get you minds out of the gutter!!

I dated in a 66 coupe and then a 65 FB. The Mustangs were a lot bigger back then. They apparently srink with age.
