Looking for blank trucks

[BCFire05]

Hey all, not sure if they're posted anywhere, but I was wondering if anyone had any blank trucks, looking for Pierce Velocity, Rosenbauer Commander, and Spartan.    Engines (side mount pump, and top mount (cat walk style) pump, and Platforms.   Credit will be given.  Needing something blank to work on designs for new trucks at work. 

 

Greatly appreciated for any help.  Thank you much.
