What's the easy way to get one of these out of a 68. Seems like there is a fastener way up under the fender that is impossible to reach without major surgery.....or is there a secret trick...

Remove the fender.... really the only way to do it....

Doh!!!
That's what I was afraid of.
Thanks for confirming my fears.

Could you do me a fovor? Can you take a picture of the A/C opening on the firewall when you pull the outside A/C box off? I am converting my 68 to air and I would like to have some idea what the hole looks like. If you manage to take the picture please post it and email it to me. Thanks.

Here's some shots of my buddies car....
