Yes your right there ash, K0 parts are commanding sandcast prices, trying to find a head and barrells for a ko is really hard now when they come up they are stupid money, i suppose they are the same as late sandast , same with wrinkle tank, ignition switch, 2 hole hub, rear guard, front gaurd, air box, carbs, engine internals, switch gear, clocks, seat, swing arm chain guard, front forks , front wheel and probably much more, infact as far as i can see the late sandcast and early k0,s only have a few differences, mainly engine cases,
