[2tons of fun]

back from the dead.


so my new project is a 3/4t flat bed that i am converting to dually and am going to use the skinny 14b to keep the tires well under the bed.

the few questions i have are

1 of the dualy factory trucks, did they use the trailing arm suspension or just leafs?

2 what is the ubolt center line on a trailing arm axle[i dont have my truck in hand yet]

3 because the axle tubes are bigger in diam than the 12b, would the ublot be able to go around the tube and throught the 3/4t trailing arm or are there different arms with wider ubolt centers for bigger axle tubes?
