Unable to find stainless 6-40 slotted flathead screws so went with cut-down socket heads.
Restored brackets with SS screws. Drilled out (1/16" & #32 drills) and re-tapped some of the screws; removed rust with Evapo-Rust and wire wheel; painted with Krylon Rust Tough rust encapsulating paint.
3/8" L 6-40 SS screws on eBay. Unable to find 1/4" L in SS.
Same screws on Grainger
Tapped a hole in 1/8" thick aluminum angle and used as jig for cutting to correct 1/4" length
