|GUESSWORKS own laygear thrust shim. As the larger sizes of the laygear thrusts for A series and A+ 4 synchro boxes reduces, a solution is to put a shim between the larger laygear thrust 22G860 and the case.|
This is a single 0.004" (0.10mm) shim.
Laygear small thrust part numbers for reference
22G856 - 0.123" - 0.124" (3.12-3.14mm)
