IDing SFI Flexplates

I came across two flexplates in my garage which I need for two motors I am building. One has its SFI cert sticker on it (pic one) but the other doesn't. Actually, it has remnants of a sticker but can't make any info out (pic 2) and another sticker with what looks to be the build date and a part number (pic 3). I was thinking that since it appears to have a build date on it, that it may be an SFI piece. Can anyone help to ID it as a SFI plate?
