On a 73 4x4, I'm surprised more didn't fail.
There was about 1/4" air under each of the mount brackets on the frame!
So anyway, the cage nut busted free on the right rear.

I am hoping someone who has done this before can tell me the best place to make an incision so i can grab that little rascal.

I am leaning toward removing the seat and cutting into the floor from above so I don't have to fear the gas tanks and fuel switch apparatus which is all right there.

What do you guys think?

It happened to me as well, you want to cut in the rise of the floor behind the seat, use the profiles of the rear and the inside of the cab as a measure, make sure you keep it back from the iside wall a bit, as the nut is about an inch and half in from the back of the cab..hope it helps

I suspected as much. How big of a hole did you need?

I believe it was about a 1 1/2 inch, just to be sure, if you measure it up right you will be right over it, Im thinking about tacking a new one in,

I used a metal hole saw, nice and clean

I'm pretty sure I have one that will leave a hole I can get my MIG gun through.

The 5 I did get done sure stiffened up the truck.
