Wheelbase?

[bigmudbronco]

I am needing help trying to figure out how to wheelbase. I am wanting to do a 290 wheelbase, and need to know what length the frame rails need to be.

290 wb = 20.7" from center of front wheel to center of tandem drives... not knowing what specific trk make you're intending to emulate?, rough guess would be close @ 28 inch length, depending on how much rail you want behind the drives.

I use this for help in scale dimensions

It's going to be a king hauler.
