1986 Buick Electra To remove replace the starter motor

1986 Buick Electra. To remove replace the starter motor from this vehicle, the "Haynes" manual says that in some cases the exhaust pipes or the frame cross member may need to be removed to get access to the starter. In extreme cases, the motor mounts may even have to be unbolted and the engine raised slightly! Could you advise me which would be the easiest choice, bearing in mind my tools are limited sockets and wrenches) and I am concerned about stripping / breaking the exhaust pipe bolts if I try to turn them!
