RB5 chassis scan/cad file?

[tsan]

Does anyone have something like a scan of an RB5 chassis bottom, or even a chassis drawn in cad? (I'd understand if no one wants to share the latter. )
I'm just about ready to start/attempt making my own mid motor chassis. It would just save me from bringing a chassis to work to scan for myself.
Thanks!

*EDIT* I'm looking for a stock chassis scan/drawing for measuring purposes only... not for an already designed mid motor design. *EDIT*
