Brake hood size?
 

I have an old Nishiki Olympic 12, not this exact bike (mine's a bit more worn..heh) but the same model and year. I've been looking for new brake hoods because mine are falling apart and was told at a bike shop that they need to specially order them. Can anyone tell me a place online where I can buy brake hoods? Or the size and type for my bike?
Thanks!
