Anyone know where to get a service or spec manual for a 366 C70 5 ton dump truck. I asked at NAPA but it seems due to the age (1979) and size they can't order them. I have several projects to do on it. First the emergency brake is missing ( but I already found a parts truck for replacement parts). I need a new carbuerator to pass smog, a new hei distributor ( someone put in an old points distributor). It would be nice to see what was originally on the truck.

thanks in advance

This one is a worker the other two are for fun!
