I bought the breather cover aluminum screws in 2019 from Fastener Express : m5x .8 x 16mm socket head cap screw 7025 t6 plain aluminum order here : sales@fastener-express.com or call Amy Boehm / Kelly Maresca 714-238 0016 or you can use the old ones unless they are stripped, just snug them and let the RTV sealant do the work
