I ordered one from Rotary Extreme, but they are on backorder:

Rotary Extreme (rotaryextreme@aol.com) has refunded your payment.
Note from Seller:
The radiator has been on back order for a couple of months. There is no
ETA. You can use the 89-91 radiator but you will need to change the
radiator hose to 89-91 and use the 89-91 fan shroud.

Can anyone verify this conversion? Do S5's have actual radiator caps on the radiators?

I'd still rather get a S4 Radiator.

I beleive thats the ticket

 

www.absoluteradiator.com is the cheapest and best service you will find on the net. just found it on there site and it's now onlyu 295 plus shipping. Great price.

 

Actually cool radiators is cheaper. 265 to your front door. My friend has one of these and its pretty sweet. I dont know how the customer support is but my friend has had no problems with his for the year he has had it

Did you happen to notice the little blurb at the bottom about these being on backorder??

Hmmm?

Only the S6, though!! <doh>
