I have to chime in here.
Not to sound to terribly harsh but....
The guys have given a ton of help, more than I thought they should/would.
If you have not read thru this forum, you should.
It is time for you to get out and practice, otherwise I am going to tell everyone to start charging for their time and advice, hell, the only thing left to do is for one of us to hop in a car and come over and do it for you.....
Good luck, you have just about everything you need to do this job from this forum, its a small job, use it for your practical experience.
