My 67 Dodge Monaco had torsion bar front suspension, rode like a Caddy. It had an adjuster to change ride height when the torsion bar “relaxed”
They were advertised not to nosedive under braking and deceleration, can’t remember if it was so.
Some later Chrysler cars had transverse torsion bars, quite a weird set up.

They were from the factory on all the F-body cars from the 80’s and 90’s (Firebird, Camaro). 

Work well and are simple.  I have not needed one on my car (no wheelhop), rear end is stable with the leafs I have from Maier and the Panhard rod.  I have enough stuff in the way of my exhaust and don’t need to add anymore puzzle pieces.

If you are trying to solve wheelhop it should work.  Might also try the style of leafs I have that have 5 leafs to the front eye which act like a traction bar.

Mike Maier makes a torque bar setup that looks clean.  https://mikemaierinc.com/products/64-73-mustang/rear-suspension/64-73-mustang-mod-1-rear-suspension-kit/

I have an '86 IROC and it made me a HUGE fan of TA rear suspensions.  It makes the back end of the car feel very stable and predictable.  Compared to a similar generation Mustang the F cars simply had better handling.  The stock Fox rear suspension was a nightmare deathtrap by comparison.

For a serious handling application it may be worth the trouble to fabricate a TA rear suspension for your classic Mustang.  For a street car it seems a LOT of work.  I've never seen a bolt on kit for a classic Mustang.  The stock leaf spring suspension can be made to work well for a street application.  You may just need different springs or traction bars.  Subframe connectors are where to start if you don't already have them.  You have to take the twist out of the chassis before you can really solve wheel hop. 

I think TCP makes one.

Every car doesn't NEED something to take the twist outta the chassis!!
