I was going to make a DVD on how to install a top. But Steve is going to beat me to it.
Still waiting for the call so I can take pictures of a GAHH top in the service position. In the meantime there are things that can be done to the clamshell to get more working room. In post #20 I mentioned the mechanic pulling back the clamshell on a GAHH car. That is what I did for the second picture.
Both pictures are my car and I have a plastic window, so the pictures are merely examples of what you can do to get more access to the engine compartment. I took these pictures long ago to show how to fix the top drive. If I had known I would be using them someday for another purpose I would have removed the engine lid.
