Just completed a WP/TB swap on my daughter's 97 Intrepid Sport yesterday. The car just rolled 100K so, I thought I'd do some preventative maintenence on it. It had a 6 bolt WP, but parts store showed it to have a 3 bolt WP for a 97 3.5L. I've done 4 of these swaps now, years ranging from 94-97, and all but this 3.5L had a 3 bolt WP. My question is... how does one ID if a 3.5L has a 3 bolt or 6 bolt WP before teardown?
