Matched Set

Depending on the country, 1971 or 1972 saw newer timing covers which differ from earlier covers. Each one matches a certain pulley.

Japan got the Timing Cover change in June 1970. North America: all A-series engines from 1972. 

Early Set
Multiple-mark Crankshaft Pulley
Single-mark Timing Cover

Late Set
Single-mark Crankshaft Pulley

Interchange

The same covers are used by A10, A12, A12A, A13, A14 and A15, except for the first type: 

1. Original Datsun 1000 timing cover, for single-row timing chain 
   13035-18000 ASSY-COVER TIMING CHAIN 
2. to June 1970, with single timing mark (pulley has multiple marks)
   13035-18001 ASSY-COVER TIMING CHAIN 
   [updated to fit Double timing chain & pressure tensioner]
3. from June 1970, with multiple timing marks (pulley has single mark)
   13035-H1000 (or from second source: 13035-H1010) 
   [Fits all A10 blocks]

Interchange is same for same. The last two will interchange if the complete set (matching pulley & cover) is used.
