The start of likely numerous questions

[inkslingrrr]

Greetings, long time follower first time poster!!! I am currently restoring my 71 custom c10, had the truck for 20years... and do plan on running a thread in the projects and build section (when I remember how to post pics!!)
Figured I'd ask a quick question before I dive into the cab area...need to do inner and outer rockers on the driver side, got outer off already(easy part) as for inner...any help with this would be awesome, I usually just jump in but it looks a little tricky>
