Modeling Imported Part

Would anyone be kind enough to redraw and model this part. Whenever i try to do it theres always somethig not quite right with my part. If someone could do it then i could see the exact steps taken in the design tree and i would know for next time. The imported part attachment is the one that needs to be re-drawn and the other is my attemt at the part.

Ive had many attempts and cant seem to make is match.

Thanks for any help you can give.
