Hello, before doing any ride height adjustments, be sure to take a look at the bolts. Have to get aftermarket as no longer available without getting whole spring. Went with silvers coilovers and never looked back.
a little silicon lube helps, GM really should have done better with either the geometry or the adjuster design. I would have guessed it was an afterthought by the spring manufacturer, expect that they kept using it for decades.
T1 adjusters may still be available. It's been a while since I needed them.

What are the symptoms of worn out ride height adjuster bolt rubber bushings? I'm experiencing a loud knocking noise coming from front end. I adjusted the ride height a few weeks ago to raise the car back to factory ride height. Wondering if my adjuster bolts and the rubber could be causing this problem.
Make sure to use some silicon electrical grease on the pads, so they last a little longer.
As for once replaced, make sure to re corner balance the car to what every ride height you want to set the car to.
As for knock, check bushings, pivots and other pivot points that may be worn out.
And yes, the stock way bar end links tend to wear out in about 30K miles to start making noise, so wise to swap a new set in at the same time (can pick up a oem set for around $100 for all 4 corners).
Here for the oem style ride height.
I tried those from 3 different places, they are all made the same and the thread pitch is wrong (really bad quality).
Actual OEM ones do not exist except used. they were never offered separately from the whole leaf spring afaik.
Sent em back and got stainless lowering ones with the swivel pads, they work really well, and ditto on the silicone grease.
my ride height was higher with those to start with so I'm pretty happy really, I needed to raise it.
99% of people would just match the adjustment length when installing new parts . We Corner balance cars for the track, this ensures all 4 wheels are carrying the appropriate load but also requires adjustable sway bar end links.
I did a simple explanation of corner balance a few years ago on my Facebook page if you are interested
