I'm looking at using the rolling chassis from a 93 D300 dualie for a project of mine. My question is; is the frame slightly narrower because of the dualie configuration? And if so, is it narrower just at the back or for the entire length? I don't have either kind nearby to measure them, and I have to act fast to get this dualie chassis.

Thanks!
