Need help finding a cartridge replacement

[waterbear]

OK, did a bit of research at work today. Hayward has a CX-1380RE cart that is used in the biggest Super Star Clear (C5500) and Swim Clear (C5520) filters. These units take 4 of them! The old number on the cart was C-1380. I found a Unicel replacement number of C-7480 and no Aladdin (Worldpool) replacement. I did not cross reference Pleatco. DrC pm'd me on troublefreepool.com because he cannot register here and told me that there are other cross references:
"The Filbur #is FC-1297, AKA # is C-1380"
He gave me pretty much the same dimensions for the filter as I saw in the Unicel cross reference 7" diameter, 32 13/16" long 3" inner diameter both top and bottom, 176 pleat count, 137 sq ft.
(his were 32-7/8" length, 7" diameter, 3" top and Bottom Centers, 150 SqFt. )
Hope this helps.
