Need tips and best practices for replacing the 5.0L Mustang (Ford 302) oil pan gasket without removing the engine.

Starting limiters:
1) Floor jacks in the garage, not on a lift.
2) Leaving engine in place.

I have a one-piece rubber gasket. I'll use silicon at the edges.

Question : do I need to remove the T5 tranny to get the pan out? Any other clearance concerns? There is no K-member as there is in a Mustang.

Thanks.
