Bolt size for rear Fender/carrier

I purchased an older 95 Honda TRX300 Fourtrax (running fine). There's 2 missing bolts that fasten the rear fender to the rear carrier. They come in from underneath and screw into a threaded portion of the rear carrier. Does anyone know the bolt size/length?

ALso, I'm missing the two bolts that fasten the front fender (both sides) to the frame. Currently the fenders are somewhat loose and flopping around. Does anyone know the bolt size/length?

Any help will be appreciated. Thank you.
