Well I started making a form to bend the fenders on. I had some strips I laminated to hold the fender outline. What do you think at first I thought it was too big maybe not. It’s about 3” gap between wheel and fender.
Your dust gates look a lot like my first attempt at them. I made mine out of MDF with nice tight clearances and you could tell when it was raining outside 'cause they'd swell up and wouldn't budge.
