Floor Measurements rear support to middle support

[Tulsa76bronco]

I have my entire back floor taken out and I am about to put the new floor and cross bar in but I don't know what the measurement needs to be from the back support to the bar that connects to the wheel wells. If I remember right that cross bar is welded to the wheel wells, is this correct? Should I weld that to the wheel wells first before I put the floor in or weld the brace underneath first on the ground then put the whole thing in and weld to wheel wells after it is sitting there. Not sure would which way would be easier.

Also is the rear measurement between the sides at the tail gate 65 inches, I found the L bracket at the bottom is not welded and just floating so I want to make sure I don't weld it down without this measurement so my tailgate will be right.

Thanks for the help

If you're talking about the parts that bolt to the body mounts; bolt them to the body mounts to hold them in their correct positions before gluing/welding them together.

No I am talking about the cross bar center of rear bed that goes from wheel well to wheel well and braces the main back floor. That brace to the back Floor Pan Cross Support Brace, Rear of Bed. Front to back measurements

This brace?

I think the four circled holes are for bolting back seat down. Can you use those to locate brace?

My brace doesn’t have holes in it to be able to line up like that but that is the brace I am talking about. I also was going to put the brace in first before the floor

This measurement
Does this brace weld to the wheel wells also

Old timer where is that picture taken from mine didn't come with the bracket already installed?

Found it with Google search for Bronco floor.
Some body part distributor I never heard of.

Try this.
Looking at online images there is a bump in floor near inner fenders on both sides that it appears the support is welded to, not the fenders. It is also spot welded to the floor at each rib.

 

[Oldtimer]

Support is spot welded to floor only

.

These three spot welds at end, on drivers side, are measured from the centerline of the rear body mount bolt.

Ok thanks so I could just weld the support to the floor before I even put the floor in

 

[Tulsa76bronco]

So then the floor itself is spot welded to the wheel wells?

I have a new floor from DC, from the back edge of the floor to the support flange edge, they set it at 20 3/8". And yes the floor flange along the side welds to the wheel wells.

I'm just wrapping up my front floor getting ready to start the rear. PM me if you need pics of the rear, I should be in the garage all weekend (if I can get it warmed up!)
