How wide are these trucks???

[Niki]

New guy here...this is probably an easy one for some of you but I was wondering how wide a '69 SWB C-10 is? I'm sure it's the same for '67 thru '72 trucks right?

The reason for asking is that I'm about to go pick up a project truck a couple hundred miles away and I called U-Haul to rent a car carrier and they asked what kind of vehicle I would be transporting. When I told them what it was, they said it wouldn't work, that the truck was too wide? So I wanted to see for myself, if one of you guys can tell me how wide the track is on these trucks I'll go take a tape measure out to U-Haul and check out one of their trailers myself. Would a 2 wheel tow dolly work better?

Thanks in advance,
Niki
