Anybody know why...

The inner part of the front torque boxes on the 65-70 cp/fb overlap the front frame rail and the convertibles don't?

I'm gonna risk sounding stupid! Maybe I'll draw the real answer!
It may have something to do with verts having different structure...inner and outer rocker panel.

At least as fast as 65-66 coupes and fastbacks didn't come with them from the factory. 67's had one, 68 and up had both.

I'm trying to picture what you're talking about. The front TB's of my 68 vert most definitely do overlap the front frame rail and floor extension.

Right after I welded it on:

I'm reading "convertible torque boxes don't overlap the frame rail".

Except they do. The only difference between coupe and convertible torque boxes is the part that meets the inner rocker.

This picture shows the left side of a coupe. Notice that the torque box overlaps the left fron frame rail tab. The second isn't a very good picture but it shows a right side torque box of a convertible. Notice that it doesn't overlap the frame rail tab to the left?

I think the one on the right is designed to be added to a car that does not need the toeboard replaced, so that section is notched out. Just my theory.

[ninedrvr]

I though something looked wrong but the catalog pictures show the same thing. The convertible pieces are narrower as well as being notched for the inner rockers.

Hey Guys, I think it is the structure of the car, coupes,fastback flooring sits on top,mounts to the side of rocker panels,as the convertible floor sides mounts from the bottom the rocker panels,so the tunnel section would need the extra support at the front of floor. [MAYBE]

for starters, don't trust the accuracy or correctness of other peoples work.

i don't know about convertibles, but i have pictures showing an original 69 fastback torque box being mounted on top of the frame rail.

Oh! Easy answer. The one on the left is a replacement torque box, improperly installed.

Sure- The inner, upper edge should be below the flange on the frame rail, not above it.

do you have a picture of an original 69 car (coupe, fastback, convertible)? perhaps different plants installed them differently (that would seem strange though).

here is a picture of the passenger side on the same car (dearborn 69 fastback). it should be easy to see the torque box is on top of the frame rail and the toe board gets spot welded on top of that.
