The Sparco 00491 custom base adapter is a starting platform for selected custom seat installations. It is intended for suitable flat-floor arrangements or installations retaining removable factory sliders, rather than a universal bolt-in fit.

Brand / model 00491 Custom Base Adapter
Application Selected custom installations
Suitable starting conditions Flat and level floor, or factory sliders that can remain attached to the vehicle
Restriction Not intended for seats using side mounts

Selection and Installation

Use an application-specific base when it matches the required installation. The 00491 needs a plan for the actual floor, sliders and seat fastening points before it can be treated as a finished mounting solution.

Product FAQs

Is the 00491 adapter a substitute for any 600 Series base?
No. It is a custom-installation starting point with specific restrictions, including the exclusion of side-mounted seats. It is not a blanket replacement for a vehicle-specific base.
Which installations does Sparco describe for 00491?
It can be a starting point where the floor is completely flat and level, or where suitable factory sliders can remain attached to the floor. These are custom-installation conditions, not a direct-fit vehicle list.
Does the 00491 adapter eliminate custom fabrication?
No. Sparco describes it as a starting point for selected custom installations. The floor layout and seat interface determine the work required; it is not an application-specific bolt-in base.
