Arch, Where are you. We need the Myth Man on the job again.
All of the following, in theory, is undoubtedly correct, hwoever, I can
tell you I have run hundreds of thousands of miles without this inner
door and never had a problem. Maybe I will tomorrow but it doesn't
matter. I'll bet some GM lawyer made the call to install the inner door.
[g]
I made a slide out for my 2 golf cart batteries 'cause they are taller
than conventional ones. This inner door, IF I had one, would not fit into
my plans. So, we need Arch to run a survey and tabulate the results.
Arch, come back! We'll behave.
