Removing the rear inner fenders

[Geos 72]

Hello to everyone, can anyone tell me how to remove the rear inner fenders or wheel wells on my 72 Chevy C10? I need to replace the wheel housings in the bed and I would assume I have to remove the inner fenders above the tires. I was looking for a video to watch but can't seem to find one. I don't have any access to a lift so I'll be doing this in my driveway. I sure would appreciate any help. Thank you, George
