Solidworks models of rover 4WD-1 parts?

Does anyone have any CAD models for the body parts of the old 4WD-1 rover that can be imported into Solidworks? I need to add some shelves to accommodate a min-itx computer as well as plan some mount points for other electronics. My plan is to start with a model in Solidworks. I found the servo motor and SSC-32 models on the Lynxmotion servo erector set CAD model page, which is quite nice, but I didn’t see any rover body parts.

I could simply measure them an produce the model myself. I thought I’d check in to see if they were already available.

Thanks,
Bob
