Just exchanged e-mails with Tom DeWitt and their annual radiator sale is on until Jan 26th. 15% off plus free shipping. Here is the link from the 2012 sale on Corvette Forum, http://www.corvetteforum.com/forums/c3-tech-performance/2985372-dewitts-radiator-sale-is-on.html. I am going to call on Monday to verify the same details hold true for 2015. Great radiators, but definitely a little pricey so I think the sale is the right time to buy if your in the market for one.

I bought a Dewitt radiator 4 years ago for the 72. Very high quality and looks extremely good in the car. I also bought their matching fan kit as well. Great company to work with. I was hoping they made radiators for my Dart I am doing but no luck. I would buy again from them and to find their product on sale would even make it better!

They are worth it.  Period.

I have a DeWitts in my 74. If I was to do it again, I would still go with them, but I would pay the extra to get the black paint.

That's what I did.  Was only another 25 bucks I think.  Looks factory.

So just clarified the 2015 Sale details with Tom - see below:

  Go for it!   I have two of them, and painted them myself.  I'm very happy.

You might want to also checking pricing through Summit Racing. I ordered my DeWitt radiator through them. I got a good price and free shipping.

already have one in my 73. I hatted having to work around the stock fan and shroud.

So my new "Black Ice" De Witt radiator arrived today. Wow it sure does look Purdy !! Unfortunately now I get to tackle the C3 version of a Rubick's cube - the '73 radiator/fan shroud. The good news is Bubba hasn't done much "fixin" on this car so the original shroud is intact. I haven't done one for a while without removing the hood but that's going to be my first attempt. That therory may change depending on how removal of the old unit goes !!
