Trouble adjusting Koni red shocks (it's me, for sure)

Posting in a new thread for visibility, I'll update the original when successful...

I'm having trouble adjusting the rear shocks to "softer"...

Here's pictures of what I have - Front are threaded on top only, rear threaded on both sides..

I watched the koni videos, none of which matches my shocks exactly but I get the gist of it... Disconnect shock, compress, push down and twist till you feel the adjuster fall in a slot, then turn counterclockwise to soften, right to harden...

Fronts were disconnected at the top only, I did not see the need to disconnect the bottom to achieve my goal. I pushed down and near the end of travel rotated the shock and distinctly felt the adjuster fall in a slot... rotated counterclockwise, full soft. Yipee... I know some said 50% F 0% rear but others said soft all around and I wanted to try that first... Front done...

Rear, on the other hand, not as fun with the access panel behind the seat and the spring around the shock... I disconnected the top and pushed/pulled down on the shock threading my hand within the spring coils to get at it. Sounds risky but the car is on scissor lift and I put tires under, etc... I could compress the shock all the way down, and rotated it hoping to feel the adjuster fall in the slot like the fronts. Nope... I pushed and turned, and whistled dixie till the cows came home, no click, no slot, nothing... Both sides. I disconnected the bottom of the shock too and completely let it loose inside the spring too, compressed it again threading my hands inside the coils, rotated from the top, from the bottom, nothign doing, no click, no slot.. WTH ???

People say "take out the rubber stop, compress..." I kinda want to ask what rubber stop ? The rubber donuts things visible on the pictures below ? those are obviously off since the shock is off... Is there another rubber stop I cannot see preventing adjstment (only to the rears ?) Why would the rears not adjust ? If I need to take out the spring I feel the job will get beyond my comfort level unless someone's got a fantastic tutorial.. So right now I'm probably full soft front, 50% rear, the opposite of desired, but hey, I'll test drive it later (can't move it right now, other cars blocking me)...

I also lowered tire pressures from 31 all around to 23F/26R as a test... Still I'm annoyed at the rears, opinions, mockery (with explanations) welcome ;-)

Holy crap, I figured it out !!

The shock towers are removable !!!!! You can take it out from the top, easy peasy in 2 minutes...
Then there IS a rubber stop inside the shock ($%#$%$%$) and you can push it down via the holes at the top of the shock with a metal rod and it eventually falls out and you pull it out because it's cut and snaps around the shaft... Then it adjusts !!! Victory !!! I may take a second look at the front one now that I know that stop can be in there but I felt the slot thing, so I guess they are out in front ? Still will recheck though !

I like it when it works out in the end !

Quick pictorial - can;t figure out how to sequence pics in the text with this upload...

undo Bottom nuts...
Push shock up (or not)
open that hatch behind the rear seat back
that shock tower is removable: not sure if that's stupid or brilliant. (2 bolts hold my entire shock to the body??)
pull up all attached..

My front shocks had no such rubber donut, only rears...

I remember trying to figure this out the first time too. Feels good when you solve it yourself though!

Yeah, but at least you’ll KNOW it’s not shocks!
