This thesis by TW Erkert has a great discussion on it,

https://ir.library.oregonstate.edu/downloads/bk128g99t.

He discussed the Society of Automotive Engineers' "Sum of Squares of Wheelbases" and other agencies' empirical methods. My temptation would be to scan and scale the WB50's template in CAD .
