The 5.14:1 axle was standard on the one ton truck. | | | | | Joined: Feb 2013 Posts: 12 New Guy | | New Guy Joined: Feb 2013 Posts: 12 | Has anyone ever heard of the 5.14:1 axle coming stock in a 3/4 ton?? | | | | | Joined: Mar 2007 Posts: 4,215 Moderator | | Moderator Joined: Mar 2007 Posts: 4,215 | Go to the tech tips at the top of this page. Scroll down to axles and you'll see how to do a swap. We did one last weekend at the homecoming event. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | Has anyone ever heard of the 5.14:1 axle coming stock in a 3/4 ton?? It is not shown as an option in the Specifications Manual. 1947 Truck Serial Number locations and decoding. What is your Vehicle Serial Number? What is your Engine Serial Number? What is your Rear Axle Serial Number? Do you have a 125.5" wheelbase? 1947 Chevrolet Truck Rear Axles I looks like the 3600 and 3800 rear axle housings were the same. It would be an easy swap/option to use the 3800 gears. | | | | | Joined: Feb 2013 Posts: 12 New Guy | | New Guy Joined: Feb 2013 Posts: 12 | Let me get all the information for you Tim,and I will be back in touch in a few days.

What is your engine serial number?
Does it match the code on your title?
| | | | | Joined: May 2006 Posts: 8,351 'Bolter | | 'Bolter Joined: May 2006 Posts: 8,351 | That's an engine number, not unusual for a vehicle from that time to be titled by the engine number. I'm finding conflicting information just as to what the number decodes to. One guide I have show that number as a 1/2 ton engine, but GM Heritage shows it at a 3/4 and 1 ton engine. Do you have a serial number for the cab?
