I would like to hook up the heat in my car when I am done the engine. The problem is, most of the heating tin is rotten and I don't have the air flapper boxes. Can these be easily replaced with better ones or am I stuck buying new ones from AA. Can you find good used ones out there?
Most of the tin I might be able to weld up and patch but I can't make the flapper boxes. Any suggestions?
