Right rear sits higher than left

[Cranky]

Ok, so I installed new leaf spring front hangers with the front eye in the 1" lowering spot.
Left side looks great but the right is still sitting up higher than the left. It's about 3/4" diffetence. Just enough for me to notice it!

The right spring has an extra leaf as it is an r/t model. I have read that this was normal for the r/t models but Is it normal for the right side to sit higher than the left? Or has the left spring just sagged.as they look to be original springs?

I am thinking about putting a 1/2" lowering block in the right side to bring it closer to the left.

The right side leaf was stronger than the left but I never noticed a difference in height but really wasn't looking for it. IF it bothers you, take out one of the leafs or crank up the LF bar a bit more. If you're using the car for some street action or drag racing, it'll help more than hurt. What I used to do when I didn't have a SureGrip is ran 10-15 psi in the right side air shock along with cranking up the LF bar a turn. On the street, most thought the car had a SG in it. Ran about 5 psi in the left just so the bag would last.

Here are some photos for context. First ones are from the previous owner.
Then my ones are the other day when I got the D windows on. Did'nt like the foose wheel look.
Just trying to get it to sit lower now.

Is there any other adjustments I am missing on the front end apart from the adjust bolt between the channel that lifts or lowers on each side? Torsion bars where mentioned. Im assuming adjusting these are the ones I am chchanging.

Yes, the bolt you are turning is adjust the torsion bar preload which raises or lowers the front of the car on each side. There is a setting for front ride height in the Factory Service Manual (FSM). If you don't have one, you can download a PDF version from MyMopar.com for free. Specs below are from the 67 Plymouth FSM
. Yours may be different

Changing the ride height affects the alignment as well.

Obviously can only post a few photos at a time?? First one above is the D windows I have put on. Rest are previous owner photos with Foose mags.

Looks to me like the car is sitting a good inch or more higher than stock....

How would one remove a leaf? If I was I would take the bottom on from the right.
Interesting part is when we went to re install the bottom plate that is connected to the bottom eye of the strut the right was no problem but the left was fully extended and still didnt want to line up easily under the leaf springs.

The stronger spring is always on the passenger side on any car. Due to the rotational force of the drivetrain, the passenger side is the primary drive wheel and the drivers side is the secondary, but only if the car has a Suregrip. It’s up a little higher on purpose, because there’s more torsional pressure on the passenger side. Same for the drivers front, it lifts first under rotational force,

Super stock springs are biased stronger on the passenger side. So are stock factory track pak and Super Track pac springs
.I always ridiculed those who said ss springs made the car sit funny, ..... till I measured mine. 1/2 higher on the right still, ten years after putting ss springs on it. I never noticed or cared I guess. Having the springs work properly was WAY more important.
If having it level is THAT important to you, talk to a spring shop, like Espo.

Ok, I think I worked it out...
I loosened the right side front and back leaf spring hanger bolts. Think I had maybe over torqued them. Its all sitting good now. Does anyone know the correct torques?
Also can anyone please identify the diff?
Will put some photos up shortly of how it is sitting. I feel like I still want to put a 1 1/2" lowering block on each side

489 case 8 3/4 rear. Tapered large pinion, crush sleeve, likely a cone style suregrip.
More likely than not, a 3.23. 3.55 is also possible.

The 1489 is what's supposed to be in it....but there's usually a tag on one of the nuts saying what gear is in it and if it's a SureGrip

The engine torques to the right and the rear end torques to the left...and is why a 'one wheel peel' does it's thing. The right side wheel gets light under hard acceleration and the left tire gets planted.

There is a tag there. Will go out shortly and get a closer photo.

Its got the 3.23 gears as per photo.
Turned the wheels while up in the air and they rotate in opposite directions so I take it this means it is not a suregrip.

Unfortunately, yep. Or, an utterly destroyed cone suregrip, but that is HIGHLY unlikely.
The stiffer spring on the pass side will help to avoid one wheel peel.
