The last time that I did work on the landing gear, I used a rope around the top motor mounting, right at the fire wall. Another was I did it, was to make a simple "A" frame that would straddle the main gear leg, and jack the airplane up at a point inboard of the oleo strut attach point, on the tri-pod. And no I didn't have the wings in place when I lifted at the motor mounts.

I know many owners don't have a clue, when looking at the universals, to
know which is which. The ones that need to be replaced don't have bushings,
and if you place one of the un-good ones beside the good ones, you will also
see that the bad ones are slightly smaller. The markings on either, are
slim to none.
Another idea for you all. If the bolts at the top of the gear are tough to
get into place and sometimes you shave off some of the bolts threads, you
may need to make new inserts with the hole on a slight angle. I used a CAD
program that I have to determine that my right side mounts were 0.9 deg
(front) and 1.3 deg (rear) off allignment. Why you say, the right main was
torn off. They did a good job welding everything back together, but the
allignment suffered.
I made a standard set of bushings, which I found out, wouldn't work. I was
cutting off threads. I put the standard set of bushings in place, while
knowing everything was off allignment. I put a new bolt in the front
attachment point with new bushings, then measured how much off-set there was
on the rear between the hole in the gear leg versus the new bushing in the
attachment point. This would tell me the angle that the front was off. I
then reversed everything and measured back to front, to give the anble that
the rear was off. I measured to 1/1000th inch and marked the position of
the off-set was headed, as in 7 o'clock, or 1 o'clock. I projected the
amount of off-set at the aft bushing versus the center of the two front
bushings. I used the CAD program to give the amount of shims that I would
need for the holding fixture for the bushing so I could bore it at an angle.
(It will draw stuff down to 1/1000 inch)
When I was done, I was pushing both bolts into place with my thumb, with a
tolerance of I'm sure this will be the first of many questions. When I received the
