Piper Arrow IV panel meassurements

Hello!

I'm planning on a "little" project for next fall. I finally have some space in my office-room and want to build a small cockpit.

My eye is on a scale-setup of a Piper Arrow IV.

I have tried to find the exact meassurements of the instrumentpanel to see, if i have enough room for a scale model or if i have to cut corners.

So far i was unable to find anything.

Does anyone here know where i can get blueprints or something like that of the instrumentpanel?

Best regards!
