HHHMMMMMM, well I got the battery tray in the problem is I cant get it to fit. Turns out the previous owner installed a radiator overflow catch can, something like this: http://www.classicindustries.com/firebird/parts/60741.html

Does the 67 have a stock overflow catch can at all? I am debating removing this or getting a separate one to relocate. So far I have not had any overheating problems with it down in hot Tucson. Any ideas or recommendations because I do not like having the battery just set in there and held with a bungie like it is now.
