Do any type of adapter plates exist for such applications (or do I just fab something up)? Or do I use a b-body sway bar? Thanks for any input!

You'll need someone to secure the sway bar at the table while you tug on the ends. I think I bent each end inward an inch. It took me about 20 minutes.

Assuming no other changes were made, such as track, ride height, shocks, springs, spring bushings, front sway bar/suspension, why not just try it before figuring out the revised rear sway bar. Nothing says you have to have a rear sway bar, they really are more for balancing the front to rear roll resistance anyway. Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

Nothing says you have to have a rear sway bar, they really are more for balancing the front to rear roll resistance anyway. Bending the bar I think is better than making silly axle brackets to fit. 7/8" on each side is not enough to make a big difference. Your just add weight to the back of the car and it may not be strong enough(the modified spring bracket and flex) Put the car together and get under there and then see if you think it is a problem, it wasn't for me and I bet if I never told you you would never even notice it under my rear end. And it sure as hell don't hurt performance because my 71 handles twice as good as my 74. My again.

Took some 3/8" X 1&1/4" bar stock (I think it was the rear front spring shackle from a ramcharger cut in two) and bolted it to the original bracket with a ball joint bolt (like 3/4" dia) and drilled a new hole 3/4" inboard.Been on there forever, does NOT move, problem solved.

Not sure if the B-body bar has the same contours as the E. I had to get a new bar anyway. remember when you said honey, some day that car is gonna look so good in front of our house

I know Hotchkis has a special bolt for clearence on the rear sway bar connector for moved springs. But I don't remember what the exact moved over amount was.

I got the same thing on my e-body with b-body rear and Caltracs. I've trimed that long link bolt since this pic. 6837615-Engineinstallation005(Large).jpg (291 downloads) 1970 Plymouth 'Cuda #'s 440-6(block in storage)currently 493" 6 pack, Shaker, 5 speed Passon, 4.10's 1968 Plymouth Barracuda Convertible 408 Magnum EFI with 4 speed automatic overdrive, 3800 stall lock-up converter and 4.30's (closest thing to an automatic 5 speed going)

With the sway bar moved 1" over there with be lateral force that can be broken down into a vertical and horizonal components. I measured the links to be 5" long, so if I did my math right, the downward force is reduce to effectively 4.9", which is only a 2% reduction in downward force. No problem that I can see, bolt it up as is and save your money.
