Available for the 280ZX 2-seater coupe, AND the 280ZX 2+2!
Sold as a pair, Skillard's engraved S130 door thresholds are made from .063" lightweight aluminum and are CNC cut. They are much more durable than the OEM plastic pieces which are old and brittle.
These will come with new stainless steel mounting screws. You shouldn't need to drill holes, but in these old cars there can be variances. If you do need to drill holes, an 1/8" drill bit should work nicely.
Skillard's S130 threshold plates are also available in raw aluminum and black powder coat. When choosing the black powder coated finish, you can select engraving options: "FairladyZ" or "DATSUN".
Please note, the raw aluminum version is just that - raw aluminum. They may have scuffs, sanding marks, or even a fully sanded finish.
