David,
I purchased one of these just to check it out. The first picture is the one I put together. I have it laying on the shelf, never use it yet.
If you notice, the front axle is a little further forward than on the Tobias chassis. Larry claims the Tobias chassis is a little too short in the front.
Second picture, with the Tobias chassis in the foreground, you can see the front axle is forward further than the Tobias.
The parts circled in yellow, I think the two on the left are rub rails. The one in the center is the dash. The one on the right I think is a nose cone, not sure.
The bottom and rear of the interior box is built into the chassis.
I put this together about a year ago. If I look at it closer I can confirm the circled parts.
Bob
