Rear main 65 hemi coronet

Buddy has a leaky rear main,asked me to do it.I'm hesitant.He is going to pick up the billet set up,but How hard is the pan to get out of the car.(stock suspension)Straight forward job ?what to expect?It's such a beautiful car, I'm nervous just not to scratch anything.

I had 3 rear main failures in my 65 coronet with a 440,the final fix with the engine in the car was to shave the factory rear cap and seal down .0010 of an inch.I was able to remove pan without jacking the engine. May be different story with HEMI!
