Brake anchor plate
Front brake anchor plate (backing plate) for the earlier drum front hub, part 37-1990.
This is the front brake anchor plate, part number 37-1990, also cataloged as W1990. It shows up in the front wheel figures for the earlier front hub setup, the plate that carries the brake shoes and takes the reaction torque from the drum brake so the whole assembly doesn't try to spin with the wheel.

On a drum-braked front end the anchor plate is the fixed backbone of the brake - the shoes pivot and expand against it, and it bolts up to the fork end so the braking force gets transferred into the fork leg rather than the axle alone. It's a wear-item-adjacent part: not something that wears out on its own most of the time, but if the fork end or the plate itself gets bent or corroded, shoe centering and brake feel both suffer.
Our records show this plate turning up in front wheel catalog entries from 1968 into 1969. If you're sourcing one for a rebuild, check that it matches the earlier front wheel arrangement noted in the parts book rather than the later version - the figure title distinguishes an earlier type from a later one, so make sure you're ordering for the right hub.
