42-47 truck heater

[Ianrhall]

Yes, I would like to get that book
The outer case on mine has no paint on it now! Looks almost like polished aluminium now, I will leave it as is, I've painted the back casing,rad etc satin black and the 3 doors green, knobs cleaned up nicely and look black, should all look like it was fitted 40 yrs ago to go with the general look of the truck!
Any reason why I couldn't fit a discreet shut off valve inside the cab rather than on the cylinder head?
