Nice to see someone else crazy enough to modify hubs like that. Although it will soon become unecessary for the Peugeots with the release of Tamiya's New Zealand 2002 kit.
Like the enhancements to the exhaust. How did you get the texture on the transmission tunnel? Looks fantastic.
I used Bare Metal Foil to build up the reinforced gravel shields. Much more maleable than OHP palstic. Good luck with the rrest of it!
