Windage tray bolts 4 needed

Do you need the main cap bolts along with the little bolts/washers that secure the windage tray to the main cap bolts? If it's just the little bolts, they should be as close as your local hardware store. Get grade 8s with the washers and you should be good to go. IIRC they are 1/4 about 1/2 inch long.
