Thank you guys! Spent a bunch more time getting this thing mocked up and everything fitting. The kit provides some styrene rod for the rear radius rods, but I elected to use Piano wire instead.
I tried to mock up the front end as is, but it just wasn't working. The parts were just moving around too much, so I pinned the A-arms with wire.
I also pinned the front wings.
The kit doesn't come with side plates for the rear wing, just a sheet of styrene. I printed a pic that has the correct shape for version I'm building and the pic just happened to print almost the exact same size. So I cut out the end plate and used it as a template. I glued the paper patter and two sheets of styrene together and cut them out together. Then I pinned them as well and attached them permanently.
Wish I was posting an update, as it's been way too long, but for those of you in Indiana, this car is actually making it's racing return tomorrow night. My brother is getting it back together to run the Tony Stewart Midget Classic at the Indianapolis Speedrome. If you're in Indy, check it out!
Thanks for looking and the suggestion. While you are correct in that the uprights are in reality hollow, the fact is that the only visible sign of that is a hole on the backside which is obscured by the tire and wheel. I considered it though, until I revisited the references...
