The restoration book I have say's that a 1970 Challenger RT 440-4 car did not get torque boxes. Only convertibles, 440+6, 426, or 440 with manual transmissions got them. Can anyone confirm this? Thanks, Todd

That is what I have always heard. And as always, there were exceptions.

A 440-4 would have them if it was a 4 speed car.
All AAR's and T/A's also had them.

My 70 R/T SE Challenger 440, 4bbl with A-32 package has them. Scheduled production date Oct 5 69.

First of all there is no accurate restoration book when it comes to Mopars, a couple of the better ones are only good/accurate enough to be useful as general guide to get you started, and some of them aren't even good enough for that!

I have personally seen factory installed torque boxes on every E-body combo the factory built. I'm sure not all of them were intentional, chalked up as factory mistakes etc. (example /6 hard top with TB's) but it happened.

Now, based on what I have seen multiple examples of (which makes one conclude that it wasn't a mistake, but rather and intentional install) E-body cars with the following engine combos "should" have recieved them:

All Hemis, all 440 Six Packs, any 440, 340 or other HP big block 4 speed combo, all AAR/TA cars, and all convertibles. I think I'd add any axle package car to that list as well.

My '70 440 U code 'Cuda has torque boxes and a skid plate. It's an automatic car with the Hemi suspension. So maybe the 440 cars with the Hemi suspension got them and non Hemi suspension didn't.

Didn't all 440 E body cars have Hemi suspension?
