This uses a 1.5 inch OD .125 wall 4130 tube for the nose gear
strut. It is bent at a 45 degree angle with a 10 inch radius.

You need to search Google for a short 2 inch air cylinder
for the damper. The latest trick in shocks is to use a separate reservoir
and the ID of the small tube connecting the two controls the damping.

BTW Zero manufacturing makes some great oil pans.
