I have been in the trucking & crane business for 55 years & have seen all kinds of changes. I recently received as a gift from my 4 sons & 2 daughters a 1955 Mack tractor. It is a B-70T with unfortunately a gas engine, which I beleive to be a EN 707C. Over the many years I have owned many Macks. From the B models to C Models & R models. This current B-70 needs a Exhaust manifod and the number I was able to get off of it is 1048049C with a H underneath these numbers. If anyone has a idea of where I could locate one it would be greatly appreciated. I had contacted Watts Mack & they said they have lots of deisel parts but not uch for gas. They directed me to this site. Any help would be greatly appreciated.
