Thanks for the info.
I will recheck the bearings for alignment.
Here is a sample mockup picture of what I had in mind.
Using a fabricated metal plate, welded nut/collar for the spring bolt.

GSO only supply 1 spring/ring per side.
I added the second, but then found the tension wasn't enough to stop the scope moving by itself.
I don't have any extra parts on the OTA, only the viewfinder and focuser.
