I have yet to upgrade the chassis on these but when I do, I'll take piccies. The big and quick fix is to pull the wheels out so that they are in the right place.
The RM tractors now have drivers, windows and a spot of weathering. I have re-positioned the windbreaker on the Cargo. I didn't realise I had run out of Roadtrain mirrors though!

Also OMWB as a couple of quickies

On the left, Ford Consul and on the right, Cortina both from Oxford Diecast. Usual treatment is to spay them with matt varnish, turn the tyres down a bit, subtle weathering and fit occupants. (the Cortina is destined to be parked) I ground off the spotlights on the consul and both will be re-registed.
Cheers
Jim
