Radiator comb?


Looking for a radiator comb to str8en things out from my ham hock fists rubbing the fluting of the radiator. i tried plastic hair combs but the spacing on the tines is wrong. Does anyone know if there is a radiator comb made that will fit the bus??? Thanks!
any air conditioning shop has fin combs (look in the yellow pages for hvac supply shops), or any higher end tool dealer, such as snap-on or matco.
