It is so damn close..
I cut off the indented top section and smoothed out the insides with a sanding bit. Still no fit.
The tube was made too small on purpose and already paper thin.
Manual sanding was out of the question. No honing tool. Getting frustrated now.
(Danger stupid brain territory ahead.)
The inside diameter needed to be reduced!!!
I did not have a lathe or chuck to shave 1/32 from the outside of the shock (thankfully), and thinking of some way to hold it while sanding down the outside on sandpaper in a hole.
Layers of aluminum foil would hold it in place in a door hole saw...right?
That was not going to work. Bad idea.
Then I tried a few hours of using an 8" flexible paint removal disk. Back and forth.
Its was marked in a spiral with a Sharpie to show what was already done.
Shock was fully extended to disperse heat. When the back side got warm it was put on ice for a few minutes.
But eventually after a few thou I chickened out.
The best and simplest solution was to cut expansion slots in the tube.
I cut a "T" at the bottom of each to allow for a "shelf".
Three or four hose clamps will finish it off.
