Can a thrust bearing be changed with the engine in the car? (318)

I have a bad thrust bearing in my 318 in my 1972 coronet. Just talked to a guy at napa who usually knows his stuff, he said it may be possible to change the thrust bearing with the engine still in the car, if I can get the oil pan off. I'll go look for myself to see if there is room to get the oil pan off but I figured I should ask here if anyone has tried it or has input on whether it can be done.

For the record, I've never done this kind of work before, this is all a learning experience but I'm lucky enough to have a few people who can help me out with this kind of thing. If you have some instructions to offer please be very specific.
