# Chevy C20 Scottsdale 350 Engine Accessory Mounting Bracket

Vehicle & Part Overview

This guide covers identification and sourcing of a mounting bracket from a Chevrolet C20 Scottsdale with 350 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 its design, this is most likely an alternator bracket or power steering pump bracket for the small block 350. These brackets typically bolt to the engine block or water pump housing on one end and carry the accessory on the pivot boss.

Identifying Your Bracket

To confirm the exact part and sourcing options, you'll need to determine:

  • Model year — The C20 Scottsdale ran from the late 1960s through mid-1980s, with significant changes to engine bay layouts around 1973, 1977, and 1981
  • Location — Whether the bracket came from the top of the engine near the water pump or lower down near the block
  • Part number — Check the back face and around any scratch marks for cast numbers; GM typically cast part numbers directly into these brackets

Sourcing Recommendations

Once you've confirmed the model year and location, check these sources:

  • Classic Industries — Carries a solid selection of reproduction Chevy C/K truck parts: https://carspanner.com/go/classic-industries
  • GM truck-specific forums — Often have NOS (new old stock) availability
  • Salvage yards — A good used original bracket is often the most economical option, since these are simple bent steel components

Safety & Fitment Notes

These accessory brackets are not safety-critical components, making quality used originals a practical alternative to reproduction parts. However, ensure any replacement bracket is free from cracks, severe bending, or rust-through that could affect secure mounting of the accessory.

Accessory mounting brackets were frequently revised across production years, so confirming your exact model year is essential for proper fitment.
