Torque Box inclosed

I have a 73 Road Runner GTX that I bought (34) years ago. I'm the 2nd owner. When I restored this car (28) years ago I noticed that the floor pan has inclosed torque boxes. I thought that Chrysler only inclosed the torque boxes on the Hemi Cars and Convertibles. Has anyone seen this before? If not I wonder if Chrysler used a left over 71 floor pan.

Torque boxes on all 440 4bb 440 6 bbl and 426 manual trans cars ... auto cars?

Transmission? didn't matter. For 71-72' b-bodies all 426 & 440 engine options received factory torque boxes, including a box plate near the rear spring shackle pivot, I would have to assume all 73-74' "U" coded cars got them as well.

Thx for the info. I had not seen them on other 73 Road Runners.

I've had two '71GTX's, one automatic and one 4-speed. Only the 4-speed had the box plates near the rear spring mount.

Strange, my 72' "U" code car was originally an automatic and it has box plates.

71X-mark.....

Were both your cars built at the same plant?

Yes, both St. Louis built cars. The automatic was built in August and the 4-speed in November, 1970.

Also, I know of another '71 GTX automatic that does not have them. Don't know where his was built.
