Timing chain kit- replacement

Hi all, I need to order up a timing chain kit. My ride is a 99 Altima 2.4L efi (KA24DE) w/dual overhead cams. I see kits on ebay, but they only go up to 97 for the application. From the pics on the auctions, it looks as if the upper timing chain is a double row instead of the single row I have. My question is, will the older double row timing chain work for my application??? I'd replace the cam and idler gears with the new double row gears that came with the kit...Would there be any clearance issues? Thanks for any info all!

Does anyone know if the 93-97 KA24DE camshafts are the same as the 98-01 KA24DE camshafts? I'm thinking of buying the earlier model timing chain kit just because I like the reliability double chain better than the single chain...
