After so many great discussion topics on streets vehicles, I thought it was time to give this a shot. The moveable wheelbase on the new vehicles allowed me to stretch this just a little. I'm still working on the finishing touches of the interior mounting brackets but it's enough right now to hold everything in it's place without movement.
The mail truck is lightweight metal - it does add a some weight versus the original car body but it seems to make it run smoother.
