They're both HK0. Only differences are condition issues. They're both UV-faded, the higher-mileage unit is further down that path. The gear-range lines on K0/HK0 speedos are highly susceptible to UV damage; they were originally dull-red. From there, they quickly fade to yellow, then white. Aside from the occasional NOS unit, you'll rarely find one that's less than 50% bleached.
