I have 4 cartridge filter. They measure 32 7/8" x 6-7/8" or 7" with 3" core hole. The model number is C-138 on cartridge. I think I didn't write all the letters down that should be part of the part number, so I want to double check, before I order 4 of these that this is the right part. I'd like to order them tomorrow.
