'97s are dual row. You have three IMSB choices:

1. Porsche stock bearing
2. Pelican bearing (beefier than stock)
3. LN Engineering IMS Retrofit bearing (ceramic)

IMHO the LN choice is better than the Pelican option which is better than stock. The ultimate fix is the IMS Solution, but dual row cars can't use it.
