Crankshaft bolt for later 1.6 Mk1 Mazda MX-5 & Eunos Roadster 1990 on.  Also fits 1.8 mk1 and all mk2 (1.6 & 1.8 models) up to 2005 .  Genuine Mazda part.

Note that this will NOT fit the very early (1989 to Sep-90) mk1 1.6 models which are identified by having 4 slots in the front face of the crank pulley.  It fits all other models (up to 2005) with either 8 slots in the pulley, or no slots at all.
