72blu asked the important question and touched on the details: what do you have, and to get that low and make it work isn't super straight forward.
out back, front hangers might get you where you want to be. more than likely, you'll wind up with a combo of hangers, different springs and *maybe* a small lowering block.
Nothing wrong with lowering blocks, especially on a cruiser. 70’s Ford 4x4’s came with 4” blocks straight from the factory, which is where the term “highboy” came from.
Like anything there are limits. Really tall lift or lowering blocks can induce issues you have to address. But 2” or less really just needs good U-bolts.
The other thing is, using the hangers to lower the car also has its side effects, lowering hangers change the spring angle which can affect the thrust angle, changing launch characteristics. Again, a small amount isn’t a big deal. But changing that angle a lot has ramifications.
Everything up front besides shocks is qa1.
Not trying to lower the front rear is my issue. I do have caltracs which I plan on taking off since this car is going more towards the cruising direction now. Not sure what type of leaf springs I have they are what was on my 71 duster when I took the 8 3/4 rear out of it .
If the springs were set up with CalTracs then they’re likely drag race springs, which makes sense given the raised ride height. They may also be stiffer than you want for a handling car.
charger426 already asked about torsion bars, and that’s important. Just running QA1 parts isn’t enough to run that low. You need much larger torsion bars, otherwise you’ll be bottoming out the suspension all the time. If you have the newer style QA1 LCA’s with the built in bump stops, you will likely not have enough clearance to the frame to run that low based on how tucked in those tires are.
I run my Duster at a similar ride height, and I run 1.12” torsion bars, the old QA1 LCA’s thst didn’t have bump stops (adding about 1” of suspension travel) and shortened 3/8” bump stops on the frame. Even then, I’m about at the limit with the top of the wheel arch opening down at ~24 7/8”.
