It's a DeWitt's, aluminum with the black coating. Stock-type appearance.1239003M is their part #.

Carpool I can't clearly see is your filler neck mounted straight up on top?

Got the Dewitt's installed this weekend. I kept the one they sent- filler neck on top. It cleared the hood although very close. It's a big core, two rows of 1-1/4" tubes. So far I am happy with results but I don't know for sure if I'll get the electric fan assembly or stay with stock fan. It still wanted to creep when idling. I sat for a bit maybe 5-6 minutes and it got to 180. Temps that day were in the mid 80's. The big difference I noticed is it runs right at 160 when driving. I have a 160 degree thermo but rarely did it sit at 160 while driving unless very cool outside. I have no doubt if I did get the electric fans, I'll have no more temp issue's. After sitting and letting the temp get to 180, within a minute of moving again, temps came right down telling me with the right CFM of air being moved through the radiator it can easily handle the heat.

John, it's after the fact... but I did find a couple of better pictures.
