Source for rubber shock mounts. From my notes:

   Original part 348-0007-00 is a hollow rubber ball approx
   15mm dia across equator, with a 12mm OD flange at each end.
   Rubber is about 1.5mm thick.  Neck OD 9mm, neck to neck 11mm.
   Clearance hole for #8 screw.  Chassis holes are 5/16" (8mm) diameter.

ACTION: Buy "DJI ZH3-3D Damping Rubber Set (Part 42)", $5.19 at ebay.

   This is four bags of four each of four different type isolators.
   The ball shaped ones (gray "A40" and white "30")
   are *perfect* drop-in replacements.

FIXED!

NOTE: "DJI Z15 Zenmuse Spare Part 7 Damping Rubber for gimbal gyroscope"

   at aliexpress is probably okay too.  6 parts $8.
   "DJI Zenmuse H4-3D Part 3 Damping Rubber" looks identical to H3-3D part 42.
   "DJI Zenmuse H3 2d Damping Rubber Part 15" at 3rdrockhobbies is
   twelve cushions (3 kinds, all ball type) for $5.
   These look like Barry Controls 275-N1 which are ~$10 each.
   Parts for the DJI Phantom series are no good; too soft.
   I don't think there ever was an H2.
