You are incorrect. 180.64.35. The first number is the unloaded length of the spring, in this case 180mm or roughly 7". The second number is the diameter of the spring; 64mm or roughly 2.5". The 3rd and final number is the actual spring rate, in this case it's in some metric measurement (newton/meters, kg/mm?!?)

700.250.300... Obviously, most of you know that is the SAE measurement (7", 2.5", 300in/lb.)
