You need one 12563532 (spacer) and six 12563533 (bolts) and the LSx dished flexplate.

There are other options from different manufacturers, but that is the setup I use.

I talk a bit about this on the first page of my Thunderbird build topic.

Since you have a 1997 transmission, if you use the setup I listed, you will be fine. You will have to elongate the holes slightly for the torque converter on the flexplate with a die grinder (ideal) or Dremel (slow). The LSx (Gen III) engines are all metric and the 1997 engines and transmissions are based off Gen I / II designs which were all US standard.

Don't get talked into an expensive billet SFI flexplate unless you are making big power or drag racing, it really isn't necessary.

Hope this helps.
