Need a measurement, A-body K-frame to floor

If you have an A-body 67-75 with 215/65/15 tires and your front end height set the factory specs (set using pivot to ball joint difference) , when you get time, can you give me your measurement from center of K-frame to floor. I am building a skid plate and to clear the Milodon pan. It needs to be 2 1/4" off the K-frame.
