how do I remove the battery hold down on a 1966 corvette

http://forums.corvetteforum.com/c1-and-c2-corvettes/2983692-changing- battery-out-in-the-66-a.html -- check out this web site. They have several different ways to get the battery out.

From what I have read sounds like there is no easy way. Might try removing tire then removing wheel well skirt to gain access to it.
