I am left trying to install the axle with no number for the wheelbase. I went to the tech tip page but I see no listing for a '49 GMC 1/2 ton long bed. Off hand I want to say that what I measured was 118" and change but this number does not match anything posted there. Anyone know what the wheelbase should be for this truck? | | | | | Joined: Jul 2005 Posts: 2,031 Shop Shark | | Shop Shark Joined: Jul 2005 Posts: 2,031 |

A FC-101 1949 model is 116" That is the short wheelbase. Does your bed have 2 or 3 stake pockets per side. If it is just 2, then it is the short wheelbase. | | | | | Joined: Oct 2003 Posts: 5,152 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Oct 2003 Posts: 5,152 | If it is a long-bed half-ton the 125.25 is the correct stock measurement. But if you are changing rear axles I'd suggest you spend some time mocking it up at the desired ride height and then position the axle where it looks best.
Most of these trucks look like the wheels are too far forward and this is your chance to fix that!

And, obviously writing it down did not help. | | | | | Joined: Oct 2006 Posts: 4,983 Master Gabster | | Master Gabster Joined: Oct 2006 Posts: 4,983 | Not a fatal mistake!
