The clip removal really was not difficult. I wish I would have removed it earlier which would have made the frame component cleaning a lot easier.
If someone is about to remove a clip and needs some specific questions answered let me know before my 67 year old brain forgets what I did.
The picture of the left cowl rust shows the only deep rust Floyd has. I don't know how to fix this sort of thing and since it is nearly unnoticeable when the fender is on I intend to just kill the rust on the cowl and on the cab mount inside and leave it. I will only drive Floyd on non rainy days and he will always be garaged so the rust should not get worse.
I really want to thank all of you who encouraged me and helped me on the clip removal.
This process was something I have never done before and my apprehension exceeded the actual difficulty.
