Upstand, you do owe tech an apology. After reading everything in the thread, I have no idea where you're coming from. I am pretty sure Bob has spelled it out in a way that anyone can understand, so it's time to look in the mirror.

Show respect to people here and you'll get a lot of respect back, and the answers you need.

You should by the way, answer everything Tech asked, as that would be beneficial information regardless of whether you use a computer to assist in determining whether you are going in the right or wrong direction with parts....It probably will save you a lot of money and time since you won't be wasting it on parts that yeild little return.
