a lot of times the pictures are incorrect any how . the best thing to do is look at the thing very car fully and evaluate the hole picture. Then get out of the box and think it over again. You know what i mean ?
think outside the box. I know that may be confusing but you'll have to do most of the thinking on your own. just think trough all the possibilities and proceed slowly. You can be your best critic if you just keep asking yourself , why would i do this , etc. and eventually you will figure it out without pictures and that stuff . just go easy and keep asking yourself why would I or should I do this and answer those questions before you continue on to the next step.

I'm just trying to get your confidence up so you can git it on. Good luck
