I found a bolt of heavy denim/canvas like material on the shelf and decided to put that under the gear stands...

I cut out another loose piece to cover it all when closed. My gears look great in the case. A few of them are in other places right now, and the ones with blue tape indicate the ratios in the car right now. Two or three more select ratios and I should have a pretty comprehensive set to choose from. Love the case - thanks Dad!
