60-40,check balls allowing bypass of fluid without going through metering valve.
the shock has to allow easier compression of the springs while controlling rebound more firmly.
The original 36 shocks don’t come apart easy with the crimped on covers and in the wingshaft there’s a thermostatic control valve that has no external adjustment later years such complications were abandoned and the external adjustment returned and they were made rebuild able with a factory built cartridge.
Most shocks can not be rebuilt to original specifications economically,the clearance in an earlier shock is between.001-.002 when new.
