VERY Rare to find! This listing is for ONE (1) 1992 Marchon MR-1 Racing HO Slot Car  SKY FIGHTER ELECTRIC AIR COMBAT JET SERIES TUNE UP KIT. They fit the F-14, F-15, BLUE ANGELS STUNT PLANE & the MIG-29. The kit includes (1) Rear end with Crown Gear, (1) Armature Pinion Gear, (1) Guide Pin & (2) Pick Up Shoes. THIS KIT WILL ALSO FIT THE ORIGINAL STYLE CHASSIS & THE FIRST RELEASE STANDARD CHASSIS. Very limited Availability. Buy them while you can. Sourced from a factory service parts center. Tires still look ok, but could probably use some conditioner.These are narrow window shoes used on the early original chassis (type 1), standard chassis (type 2), sound/light chassis (type 4) and jets (type 6).  They cannot be used on either the revised chassis (type 3) or alternating current chassis (type 5).  With a little work, these could also be used on the monster trucks (type 8).  Be aware that the window area on these shoes may be too tall for some bodies and need to be bent in order to allow complete freedom of movement.  The spring system is similar to a Tyco HP-7. Please note: The rear spacer on the left side of the Crown Gear may need to be shaved away to accommodate the jet fighter chassis shell.
