I do in fact have a replacement bulkhead that I got from DennisM. It has some minor repairs that need doing, so the firewall, windscreen, engine, seatbox etc will come out as part of the restoration.
Not a complete strip down though as I have no desire, or equipment to, remove the ambulance body. But everything else that can come off to be worked on will. Once the engine, firewall etc are all done the front axle will come out, and so on and so on. Exterior and interior will be the last on the list. I'll get it going first!
The red paint is a rust preventitive / primer. THe red makes it easy to see where you have covered, as well as when you have covered it. I could have gotten it in any number of colours, but I like using the red on the chassis for the above reasons.
