Difference between 68-69 fan shroud and 70+ fan shroud

[Corellian Corvette]

I just purchased one of these aluminum radiators for my 68 Charger w/ AC

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=150337911137

I would like to get the correct shroud. My car does not currently have one.

It's my understanding from searching that the only difference for this radiator is that it uses the 70 shroud, but I have never sen pictures of the difference.

Can someone confirm this uses the 70 shroud?

Thanks!

LOOKING AT THE PICTURE,IT HAS 4 HOLES FOR THE SHROUD LIKE A 70. A 69 SHROUD HAS 2 BOLT HOLES ON ONE SIDE AND 3 HOLES ON THE OTHER SIDE. CANT TELL FROM THE PICTURE IF THE HOLES ARE DRILLED IN THE RIGHT PLACE FOR A STOCK SHROUD THOU.
