Guys, I went thru the strut rust/take off and honed the strut cylinder/removed 
the rust on the piston cylinder, then replaced the pieces of rubber left of the 
cup with new cups (Skyport).  Now the real problem came when I tried to push 
the strut tube back up on the cylinder piston. I did not want to remove the 
piston from the wing - looked like I would have to remove the wing to do it. 
  Anyway, because of the bell-shaped top cap on the strut cylinder tube (held 
on with a snap ring), you cannot get to the insertion point on the top of the 
strut cylinder to persuade the new cup to start into it.  Liked to killed me 
before I finally asked for help.  My mechanic and I finally rolled a 5" wide 
(or so)sheet of stainless steel shim material (Very thin - maybe .010) into a 
tube, oiled it up good with fluid, stuck it down thru the bell top cap into the 
strut cylinder, and used it to guide the new cup/strut into the top of the 
cylinder, and then worked the stainless guide "sleeve" back up and out and 
unrolled to get off, then pushed the strut together.  WHEW!  Let me tell you, I 
am careful not to pull the cylinder down too far when servicing!
To service:   jack up (see the pix on my jack in the posted album), remove the 
gear strut bolt, then VEEErrry carefully rotate slightly back and forth and 
pull the cylinder down until the cup is just barely above the fill cup. 
Careful, because you DON'T want that cup to pop out again!  I check it by 
putting a scriber gently into the cup to see if I'm still on the piston.  When 
the scriber goes on in, I know I'm below the cup.  I use a pumper oil can with 
a WD-40 "straw" stuck into the tip which I stick all the way into the fill cup 
and into the cylinder, and pump in my brake fluid until it runs back out (it's 
full).  Then I push the strut cylinder back up and put the bolt back in.
By the way - if I remember right, I had to make the jack raise 14" to get the 
tire to clear the floor.  That's why I built my special jack (again, pix are in 
our album on line)
