I had bought the kit and knew from reviews that the skate rail brackets were wrong. I had decided when buying it to fix them. I didn't realize that it was harder than I thought. I finally finished correcting it mostly. Unfortunately it obviously isn't wholly accurate as I eyeballed the design and I had to shave a lot off the rear bar in the back... Not sure what to call it. You'll notice it next to the new PE brackets. If I didn't shave it down the brackets wouldn't connect with the rear wall of the model. I wasn't going for complete accuracy but more of a "it looks right so it's fine" correction. The first picture is how it looks in the vehicle and the second is how it looks on its own. This is the first actual scratch building/correction that I've really done at all.
Also without those places that you see against the rail the brackets wouldn't connect and it would've been harder to keep them attached.
I also have a picture of the unditching roller here. I wrapped it in string to try to simulate rope wrapped around it. What do you think?
