Depending on what you run under the bonnet, but I would get the original redone.

Its not that expensive to get it all done in new again.

If you want an more cores than the standard 2, you can use two top tanks to give you a 3 core radiator.

The top tank is wider than the bottom one, so get the radiator dude to swap the bottom tank out and put in an extra core while he is at it.

That is what I have used in the past and its a winner. Never had cooling problems again, even with the nealry useless standard fan.

wot types from other cars would be a good
