Rear view with the ill advised window:
And the opposite side view:
I'd like to show how I've been working my edges. They need to be rough, but I didn't want to agonize over the detail. A little goes a long way on the guys and it's easy to get carried away.
I start by using my cylinder cutting bit to carve a bevel on my edges. My main aim here is to take off the square edges.
Then, using the edge of the bit I carve rough "crinkles" in the bevel. I move the bit along the edge as well as letting it drift onto the flat edges of the body.
The rear fenders I mounted directly to the tire. I cut the bushing out to fit on top of the axle. I rotated the fender around the tire until I got the best fit, the glued it in. I trimmed the rivets off of the three struts as these were going to mate right against the body shell. I glued at these contact points as well as the wheel, just as normal.
I decided on straight pipes for the exhaust. They are super easy and fit the look well. Just plastic tube with and angled cut on one end.
