I bought the doors at west Marine. *Did the port side first so I could mount my kicker bracket. *I made a cardboard templet of what I needed to cut out. *Positioned the templet where I wanted it and marked the fibreglass . *I *then used a rotozip tool to do the cutting. *Two hands on the rotozip, slow and steady.
