Neither, make or buy some clamps for your front spring segments. Id suggest two on the passenger side front, one on the driver side front. And also maybe one each on the rear of the axel on both sides. Thanks for the Reply, Not sure what you mean by Clamps !!! Tom C.

Spring clamps http://www.manciniracing.com/caspcl.htmlSimilar to what the factory used.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

These are not the type of clamps im referring to. The clamps are more like two flat steel bars tightend by bolts that are just beyond the width of the springs. Much more clamping power then these clamps shown in the link. IMO, Clamps or different springs are your fix. 1.El cheapo, clamps. And they can work. 2. More bucs, SS springs 3. Caltracs.

Caltracs are noisy and much too harsh on a street driven car. They work phenomenally on a smooth race track. Pinion snubbers, when properly adjusted, are way to harsh on a street driven vehicle. I learned this from several decades of experience.
I run slapper bars on my '68 Barracuda with two passenger side Super Stock springs and a 1" lowering block. I had to modify them so they were adjusted properly.
I know, I know, they don't work on Mopars. LOL
I guess the reason I just beat a Hellcat in a flag drop drag race to win the Willow Springs Drags at Spring Fling was my GM 200R4 transmission. My car only had 410 hp at the time too.
The bottom line is they work awesome, ride only slightly stiffer and if you paint them satin black, most people will not tell you how they don't work.
Even Bob Tarozzi, the designer of the Super Stock Springs signed off the set-up of my car. He said they didn't use them because of weight. A pinion snubber is lighter and works great on a smooth track.

Wheel hop is really hard on all of the drive train parts, driveshaft, tranny, rear end, U joints axles and so on, not good I would replace the existing leaf springs with better ones, what kind of driving do you do mainly to induce wheel hop? Is it a 4 speed or automatic? Pinion snubbers where intorduce on Mopars in 1957 when they lowred the cars closer to the ground to prevent the pinion U joint from hitting the drive line tunnel, not for traction Fix the problem, don't bandaid it

Pinion snubbers, when properly adjusted, are way to harsh on a street driven vehicle. I learned this from several decades of experience. I'd have to agree here. I added a Pinion Snubber to my 440 4-spd car, and it launched awesome. However, in normal driving it was a major pain. I took it off. I was and still am running factory 440 replacement springs in the car. But, if I wanted to race more, would definitely consider SS springs.

Your car looks kind of high in the back for stock hemi springs. Does it perhaps have airshocks on it? If not then are the shocks long enough? If they are airshocks or if the shocks are topping out then you will always have wheel hop.
In theory, there is no difference between theory and practice. In practice, there is.

I was and still am running factory 440 replacement springs in the car. But, if I wanted to race more, would definitely consider SS springs. I'd like to see someone like AndyF develop a retractable pinion snubber, so it can be deployed or retracted on the fly from inside the car. Something simple and robust that locks in either the extended or retracted position with the flip of a switch. It would need to have some range of adjustability, and when retracted stays out of the path of the suspension movement. It seems like even a cable operated knee-like lever inside the snubber body would work.

On your deal buy a good set of leaf springs designed and intended to be used like you want I'm not sure if Mopar still offers a set for a 1964 to 1970 B body 4 speed car for all around high performance drinving like you want to do I bought a set of the Mopar S.S. road race type leaf springs for my 1966 Coronet, they are the shorter front half length like the A bodys are so the front spring hangars would need to be replaced to keep the rear end in the stock location if you want to do that. I didn't use them as I moved the leaf springs into the rear sub frames and moved the rear end forward two inches, which required reshaping the front fender openings I'm sure your leaf springes are worn out so replacing them will help the car a bunch, if you want to try a new set first before adding clamps do that If you want to add the clamps later I use 1/4 thick by 1.0 inch wide flat stock steel and drill 3/8 holes in them on each side and use 3/8 bolts of the proper length for each clamp, I place them on the front half of the spring in every where I can (the tire bulge will, may, hinder using one on each side near the tire bulge ) on the front of each shorter leaf springs to clamp it to the main leaf. Do it with the weight of the car on them, don't jack it up on jack stands with the rear end hanging down You can jack it up and put jack stands under the rear end axle tubes and under the front suspension so it has the weight on the suspension to do that to be able to get under it to work on the car Let us know what you do and the results

Seems like many options have been laid out for you. There are many ways to resolve this. We can all agree your current leaf springs are too weak. Stiff shocks help too.
The solution with the least drawbacks is a pair of Super Stock springs and a pair of stiff shocks.
A pinion snubber remove ALL suspension travel on the street. As for the clamps, leafs want to slide. You need to clamp these hard enough to force them not to because they want to. When they do slide, the clamps wiĺl hold your car down after suspension compression and hold the car up after suspension compression.
