You might consider cutting the rod and mounting a piece to each wheel. Then use that to glue the rear wheels to the rear axle. Unless the axle housing hole is to large, then you could either bush the axle with hollow plastic tubing or drill the wheels for a larger diameter metal axel to match the housing.

The cutting and gluing sounds like the back wheels won't move. I might have to go down the larger rod path, I went to my local hardware store and you'd be surprised how hard it was to try and find 1mm thick rods ..who knew! I might have to Macgyver my way through this, thanks for the tips! Here's another picture for you all.

The chassis looks nice. Are you wanting to leave engraving on the floor pan ? You mentioned the axle issues and wanting the wheels to turn. That's alright if that's what you want, but there is always the possibility that the model could roll off the shelf if the wheels can turn. Usually they are glued in place to prevent that from happening.
