Help!!! Oil pan replacement for a '99 3.2 engine

I assume "main crossbolts" means bolts of a main frame crossmember. If so, then no. The only thing structural that touchs the pan besides the bottom of the engine block is a piece at the very back of the pan called the "structural collar". It bridges the gap between the bottom rear of the enigne and bottom front of the tranny.
