Back on page #11 the last post from the OP says;
"Now we're going to spend some time reading all this slowly and taking notes. Thanks to all for this tremendous wealth of information. You're all very generous with your expertise and we do appreciate it."
Now on page #15 the thread has gone the way many do such as nit picking spoons comments about old vehicles and has no informative value for the OP questions.
The OP has asked several questions on this and other threads and has pages of comments. At some point they will have to make a decision on what they want to do.
Wish the website had a dead horse clickie.
