I am here early and hopefully will save a lot of people some breathe. A lot of people that do cads, will not, freely pass on a cad file to someone or make one for someone. I am willing to draw one up for you for free if you can't find one but let there be warning now, asking for that here is sometimes doomed one of the deadliest sins. The amount of time and effort it takes people to create those, it offends them when some people ask for them and don't put in the hard work or pay for their services.
As I said before if no one has one that they are willing to share, or you can not find one on the web, I am willing to draw up a p-bass for ya.
