There was a web page that had a very good set of progress pictures on a TT. I think it was to be raffled off. I can no longer find it. I thought it was on the TT truck web site but its not there. It had a wood firewall and it had some great pictures of the firewall wiring I need to copy.
Scroll down to:TT progress pics.
Is that it?
That was a TT Truck restored by Mark Williams, and his many helpers, for the MTFCI Youth Foundation Raffle. If you go to the MTFCI forum, which is run by Mark, he can probably help you out.
