The rubber cup was an SK kit from either skyport. It is the standard part that was used on early coupes. Later coupes went to the o-ring. It is Skyport kit SK-61 $25.95 It adds (replaces) the o-ring with the rubber cup used in SN 812 and earlier coupes. I believe it comes with all parts and instructions. I left the o-rings in (new ones) and get the best of both. I rarely have to add fluid to my main gear David Abrams Galactic Industries Corp [EMAIL PROTECTED] > -----Original Message----- > From: G/F Alon S/N149 [mailto:[EMAIL PROTECTED] > Sent: Sunday, September 17, 2000 3:19 PM > To: David Abrams > Subject: RE: [COUPERS-TECH] Landing Gear > > > Dave, I am going to do both of my hydraulic struts this > fall.
