Glareshield Dimensions Question

I am building my B737 based on dimensions published by MarkusPilot. According to the docs, the lower part of the MCP should be 995mm from floor. It should extend 310mm from the glareshield. Using the 15 degree angle, I cannot get the glareshield to be both 995mm from floor and 310mm from MIP. In order to get it 995mm off the floor, the distance from MIP to MCP is 80mm. That's 1/4 what it should be.

Am I interpreting the diagrams in markuspilot's documents? Any suggestions on how to get the MCP dimensions correct?

Thanks,
Steve
