Hi All, I'm new to the group here. I'm getting ready to start restoration on a pair of old AC 4 Cylinder Macks. I believe the year is 1916-1923. As you can see they have a long way to go and I will know more once I get them out of the black berries bushes. I restore rusty stuff for a living and this is my latest job. When I'm finished there should be two trucks out of this pile. Anything I should know about these old trucks before I dig in?? What is the best way to pin down the year?

Well they aren't as old as you think, as they have the later radiator design. The second one looks to have the optional larger ac-6 radiator. If you don't have the Id plate by the passengers feet in the cab the serial number should be located by the front right tire stamped into the frame. Write the Mack museum with those numbers and they will provide you with all the info on the trucks such as specs, year, and who it was first sold to. Also, you should get to know Gary Mahan in nj as he is a wealth of knowledge and parts for early Mack chain drives. Good luck!!

  • The serial number is on the top of the frame on the left front (drivers side) side.
