I have this aluminum 7 blade fan that I have been trying figure out what it goes to. It measures 18-1/2" Dia.
Marking on all the blades are DD CD AAHJ L66
On one of the blades is stamped 912773 SC-M66
I searched the Internet and found that a few years ago on another Mopar site. Someone else had the same fan and was asking the same question, but came up empty.

Here's a Mopar 7-blde fan that's claimed to be correct for a '68 B0/L0 Super/Stock HEMI car.

$110 on eBay

..... and that's "DP CD" & maybe "L66" = November '66?

close but not quite - maybe its a '67 S/S R0/W0 fan?

Dan,
I saw that one also on ebay and at first thought it was the same as the one I have, but then saw the difference in the blade attachments and rivets. Maybe the difference between the two is that they came from two different venders, but have the same application? Another guess...
I was planning on selling mine, but I'm not sure if it is a common fan or if it one for a special HP application. In other words, WIW..

A-864 and A990, and possibly max wedges used the 5 rivet aluminum fin fan, but with the 64 or 65 date code. Your 66 date could be a replacement part for these motors or found their way into the 67 Ro/WO cars?

If that is a correct fan for a 1968 Hemi dart car I would be very interested in purchasing same. PM me if you decide to sell. Thanks.

My Dad's 67 New Yorker, 440- TNT, w/A/C has the 5 rivet aluminium fan on it

I noticed the aluminum fan on some original pictures of Hemi A-Bodies but can't imagine running a fan like that on high-horsepower applications. A friend just had his clutch fan come apart while driving on the street, luckily it didn't hit the radiator!
