1979 Pontiac Firebird Seat Mounting Diagram - Rails, Spacer & 8mm Bolts

This document is a simple hand-drawn schematic (line drawing) illustrating how an aftermarket or swapped seat is installed onto a vehicle's factory seat mounts. The drawing shows a side profile of a seat sitting on its included seat rails. Below the seat rails, a steel spacer is shown, which sits atop the factory seat mount (drawn as an angled bracket profile). At the bottom, two 8mm bolts with washers are shown with upward arrows indicating they pass up through the factory seat mount and spacer into the seat rail assembly. The four labeled components, from top to bottom, are: seat rails (included with the seat), steel spacer, factory seat mount, and 8mm mounting bolts. The diagram contains no text identifying a specific vehicle make, model, or year, no part numbers, no torque specifications, and no dimensions other than the 8mm bolt size. It was uploaded to a 1979 Pontiac Firebird gallery, but nothing in the drawing itself confirms or contradicts that application. A reader can learn the basic stack-up order of hardware for mounting a seat using spacers over factory mounting points with 8mm bolts.
