I can find the front spring hangers for stock location and to lower the car.
Yet none to raise the rear of the car ?

Any options avail to lift one. Maybe 1.5 is what Im looking for

The car has new Mopar perf leaf springs and it just sits to low. The tires rub up inside the tub area on bumps

I'm not sure about 66 but some spring hangers are Dodge or Plymouth specific as it changes the wheelbase between models...

The ones I bought for my 65 I think have both sets of holes with a set to also lower the front spring attachment...

I don't ever remember seeing ones with lower holes that raise the rear ride height...

However they could be easily made from a stock set and some 3/16" flat plate...

Might try looking for something for a drag racing application.
Or, there's having your springs re-arched, or the SS springs, or the Hellwig EZ-550 helper springs...

I am pretty sure that the 4 mounting studs are wider apart at the bottom instead of the top but could you possibly modify and invert the hangers?
Maybe sandwich the modified hanger between a 1/4" steel plate and the car body for extra strength if you feel the modifications need reinforcement?

On a side note since the spring pivots on the rear hanger you will have to lower the front bolt a lot more than 1" to get 1" body lift. Getting 1.5" might require lowering the front mount and the rear hanger 1.5" at the same time.

I'm thinking re-arching the spring would be the way to go. Possibly some helper springs/air bags might work too.

Dare I say it Air Shocks, not pumped too much but just for the little lift. (Let the mud slinging start for me offering the suggestion of air shocks begin)

IF you do go the air shock route I suggest putting separate fill points for each shock to prevent air from migrating shock to shock.

Go to a narrower tire or get a wheel with more positive offset. 7.75 X 14 were the stock tires on a '66-'67 Hemi car, not a lot of rubber in anyone's book.

Its not the hemi car I need to raise. Its my other 66, 383 auto.
Im looking for the least expensive option to lift the ars up.

Tires are like new so thats a last resort.
Air shocks are my option.

The leaf springs are / were new Mopar Performance " hemi " springs. And the car sits a good 3 inches lower than my black car and its on stock original hemi springs
Its sitting on 15x7 torque thrusts with 245-60-15s and the outer sidewall rub up in the wheel house NOT on the lip. So its at least not cutting the tire up,,,just leaving ugly rub marks on the sidewall

Yeah, that's low - like those springs are dead.
I think the EZ-550 helpers will be less expensive and better than air shocks.
Unless it's a contour up in the wheelhouse you can "persuade" away from the tire.

Back in my younger days, we used to add longer side brackets for the rear shackles. There used to be longer shackle kits available that were plenty long. I would lower the spring about 2" per side (holes were drilled at 1" increments), then I cut the bottom of the shackles off below the bottom hole I used. If we went for the max lift, it was good for about 4" of lift. Shackles were a lot cheaper then air shocks and didn't change the pinion angle enough to be concerned about. By far the cheapest way to gain a couple inches of lift.

The long shackles were nothing special. most were 1/4" thick x 1 1/4" or 1 1/2" wide bar stock with two sets of 1/2" diameter holes drilled through them. Two holes per side are all you need. One hole the bolt for the frame bushing goes through, and the other hole is for the leaf spring bolt at whatever spacing you want. The holes need to be centered at least 3/4" away from the end of the bar stock.

I understand fully. I just use the Hemi reference as it illustrates how little room is in the '66-'67 rear wheel tubs. And I know exactly what you are hitting, the outer wheel house goes vertical off the wheel opening and then narrows toward the center of the car with a "bump". After this narrowing is where they always rub.

As to what to do, maybe this would work rather than air shocks

Coilover Shocks

Advantage: Install them and forget them

Disadvantages: Can't be adjusted (unless you get the really high dollar units.

Just a question, do the springs have a negative arch, positive arch, or flat? IIRC, the stock springs should be flat to slightly negative.

Springs in this car are flat as it sits ,,,,notice the rear shackle
. And the label was still on them
Ive thought about the coil overs. Just concerned is getting it to high.

As ipposed to the spring arch and shackle position in my other car.

Yup, they're dead: note the reverse arch near the shackle.
Shackle tilts rearward as spring gets longer...because it's flattened out.
Those look like regular 383 springs; I see what looks like 4 leaves.
The Mex-made springs have been infamous in any case, for just that issue.
The EZ-550 helpers I mentioned are the least expensive fix.
Best fix is ESPO/Springs&Things Hemi springs in stock height, or +1" if you carry lots of stuff.
The ESPO Hemi +1" on my '68 RR have the car a bit higher than OEM.

Just got a quote on new springs from ESPO.
About $420 for a pair delivered to my door.
but need to be made ,,,,none on hand

need to think about that

another thing popped out at me when you posted a picture of the label. "made in mexico"..............
almost everyone i have talked to, listened to, and had experience with, those springs [and others, especially the super stock springs] made there had bad comments.
espo springs have always had good comments to my knowledge, so if you are considering them, a +1 or +2 might be a thing to consider. however, all springs will settle a small amount after the install, so keep that in mind.
as i said before, you could always add a leaf [or two] to the spring package you now have from the springs you removed, and all it would cost is a couple of dollars for new center bolts.

I dont have the old springs.
I bought the car like it is this past Aug.

Or I would be switching back to the stock springs

I think I will order some air shocks today. That way I control how much lift I put in it . Wrong time of year to be spending $400 on springs
especially on a car Im not 100% sure I will keep ( the bug for a convertible is getting strong )

air shocks aren't meant to hold the car up. You can buy an extra leaf online. https://www.summitracing.com/search/part-type/leaf-spring-add-a-leafs

If you were at the 'stock' ride height, I would share your concern. But as much as it's sagging, I don't think you'd have a problem. The NAPA units are rated for only 1,100 lbs of additional support so I can't believe that you'd be in the air. The saving grace is that with either the coilovers or the air shocks, the upper shock mount on the '66-'67 is substantial so I doubt that the upper mount would be coming through the floor.

Another vote for Espo if you decide to go that way

Did you look up that part. Number? Are those a bodie springs ? Made that mistake once . Shackle angle looked just like that .

A couple of long leafs would solve most of that problem. might need new U bolts and will need a new center bolt. Air bags between the frame and the leaf spring would also work and are adjustable. You can do them on an air line like air shocks are done, or you can invest in the air compressor kit and change the height from the set of the car. The compressor kit would probably get pretty close to the cost of replacement springs.

The shock mounts were not designed to carry the weight of the car., but for what your doing it will probably be OK.
