55-57 Chevy 2-Door Window Regulator Idler Bracket.
This bracket mounts to the inner door; it is used to help guide the window regulator. The bracket is 6-1/2" long. This is the track that the window regulator rollers rides in. Two needed per car, one per side. Made from galvanized metal, so they won’t rust. Works on all 55-57 Chevy 2-Door Car & Wagon Models. Made in the USA.
