Model accuracy & scope

Reviewed exterior models with fitted geometry. Installed part numbers and component-level manual matching remain unverified unless explicitly identified.

  • Reviewed first exterior; dimensions, routes and materials include fitted approximations. Not exact installed OEM geometry.
  • Parts groups are a browsing aid, not an OEM exploded assembly or an installed parts catalogue.
  • Internal mechanisms, functional flow and maintenance fit are not established.
  • The F flange and historical -12 accessories are represented; later -14/-16 equipment is not.
  • Small pushrod/head and mount-lug fit relationships remain deferred.

Use the applicable manufacturer manual and parts catalogue for maintenance and exact installation details.
