Hardware parts

Hello all,
Is there currently a list of easily accessible Axis parts at local hardware stores, Amazon, etc? I have found spring washers for the bolt lugs at Menards, upgrade extractor ball at a bike shop, and Amazon.
I know that trigger upgrade parts are available... washers, spring, but I don't have the specs for those specific parts. If anyone has them, please add.

Extractor ball bearing upgrade : 3.5mm /.140 / 9/64th
Trigger screw is a 10-24 x 3/4 hex head set scew, if using a non binding spring.
Trigger pin washers: .014 thickness, .145 ID hole, .387 OD
Trigger return spring upgrade: .016 wire diameter, .778 long, 10 coil.
