Thanks Frank

I'll have a look for the plate, But with army trucks thing seem to go missing. The plates on the british army trucks here are on the seat box and the brake booster housing. I've had a few army rovers that had both seat box and booster swaped with those from other rovers so the only way I could tell what the real serial number should be is by looking at the Chassis in the front wheel well. I like the idea of spacers what would be best aluminum or steel.
and would 30mm be enough.
