# 1986 Chevy C20 Scottsdale 350 Engine Accessory Mounting Bracket

Vehicle & Part Overview

This is a mounting bracket from a 1986 Chevrolet C20 Scottsdale equipped with a 350 small block engine. The bracket is a flat steel plate with three fixing points: two plain bolt holes and one threaded boss welded or cast into the corner.

Based on the mounting configuration, this is most likely either an alternator adjusting bracket or a power steering pump mounting bracket. Both use similar pivot and slot arrangements on small block Chevrolet engines and can appear visually similar.

Location & Function

  • Alternator bracket: typically mounted driver's side, upper engine bay near the water pump
  • Power steering pump bracket: mounted lower, toward the front of the block

The bracket bolts to the engine block or water pump housing on one end and carries the accessory on the pivot boss.

Identifying Your Bracket

To confirm which bracket you have and locate the correct replacement, examine the part carefully:

  • Check the back face for any cast or stamped part numbers
  • Look for numbers in the 14000 to 14100 range, which is typical for small block accessory brackets from this era
  • Clean any dirt or corrosion from the area around any visible markings
  • Take a clear, flat photograph of the marked area

A confirmed part number will allow you to source the exact correct replacement rather than guessing.

Used Original Parts

If reproduction brackets are discontinued or cost-prohibitive, used original brackets are a practical alternative since these are not safety-critical components. Used brackets regularly appear on:

When purchasing used, verify that the seller's photos clearly show the bolt pattern matches your bracket exactly, as GM revised these brackets multiple times even within the squarebody generation.

Fitment Notes

The 1986 C20 Scottsdale with a 350 engine falls within the consistent squarebody engine bay layout period (1981–1987). However, the 350 may be either:

  • Throttle body injected (L05) if built later in the production run
  • Carbureted if built earlier

The fuel system does not affect bracket fitment, only what accessory is mounted to it.

Note: Confirm the exact location where this bracket was removed from your engine bay before ordering a replacement to ensure correct fitment.
