[hilljob26]

i bought this truck as a parts truck,,has a mark 4 underdash a/c installed and a funny dome light,,also there is a toggle switch for the fuel as it had saddlle bags on each side of the bed.truck also has 8 lug 15 inch wheels,,i will be strippin this down pretty soon,,just lookin for an idea of what to ask

it says on the glove box that it is a switched dome light,thats what makes me think its factory that way..and was also told that the a/c was a dealer installed item
