The Zinc Bolt Kit for your NA/NB Miata is finally here! Full list of what bolts are included is as follows:
Rear Main Housing
Oil Pan
Oil Pump
Water Pump
Water Pump Pulley
Coolant Neck (To Head and Thermostat Cover)
Timing Backer Plate
Timing Covers
Intake Manifold (Nuts for Studs on Head)
Exhaust Manifold (Nuts for Studs on Head)
Valve Cover
NOTES:
These are not OEM bolts, they are aftermarket and not JIS. I've been using these for years without a single problem, but the bolts that were 12mm heads (all of the M8's) will be 13mm Heads.
I can't find the long oil pan bolts so those will not be included
Zinc coating is not always uniform color across all of the bolts as they are done in different batches by my supplier. You can't notice when they are all installed, and all shared bolts (ex: Oil Pan Bolts) will all be from the same batch.
