for about 130-180. you can get an all aluminum radiator.
go to any radiator shop. they can get you one for a good price.

I got mines a couple years ago. and it still looking new. no leaks. Doesnt cool the car as much as the (showa) radiator though. (showa the one with the tan top plastic piece). they are the best radiator.

better then the (denzo) black platic top piece.

The showa radiator is about twice and thick as the denzo. (these are stock radiators).
