55.2-59 Firewall dimensions

[regan56]

Moving along on the build and I’m now to the point where I can mock up my engine and trans placement. I don’t have my cab near me so I’m going to try and mock a firewall to give me some perspective on how close the engine can/will be.

Is there anyone that can give me a few simple measurements?
- from CL of front cab mount to face of firewall and to the start of the bottom of the firewall at the floor
- location of the bend from top of frame rails
- distance from outside of frame rail to the tunnel edge
- total tunnel width
- height of tunnel from top of frame rails or the bend
