C3 Battery bracket
Be sure to neutralize that acid, not just rinse it out.
The hold down is a wedge that grips the bottom of the battery. The front sits under a lip. But this requires a specific battery to work.
Here's a link to the hold down at Amazon. You need the bolt, too, or you could likely find something at the hardware store.

Cool thank you. I found the part online just wasn't exactly sure how it held the battery in from the pictures of the parts.

While you are at it, be sure to pick up a shop manual, and assembly instruction manual, specific to your 77. And please consider starting an intro thread with photos!

Being well aware of the ads that tell you that you can mount the newer Absorbed Glass Mat battery in any orientation and it will continue to work. It is not true as the batteries are made with a level ground plane under it. The placement of the AGM batteries favors the conventional battery orientation where Gravity helps keep the plates covered in Electrolyte. The electrolyte in an AGM battery is thick and more like tooth paste in consistency and it doesn't move very quickly. In many positions other than on a flat surface the battery might have inner plates exposed to oxygen and this might lower their capacity.
My battery compartment is thermally insulated and has the standard bracket on it to keep the battery in one place like most 1968 Corvettes. I like to use a battery strap that is attached to something solid like the frame or a cross-member and the battery in a plastic battery box is secured inside the battery compartment. I have a marine grade DC circuit breaker in between the accessories and the battery itself. Being involved with boating I like the requirements for securing a battery inside a marine vessel. Keeping a FLA battery on a boat it would need to be inside a battery box that is securely fastened to the vehicle. The battery should not be able to "get loose" and hurt you even in a bad accident because it is secure. With a cover on the top it is less likely to start a fire which is even more protection. I have an early 1968 C3 and there are a lot of things that started of as fiberglass that were replaced with steel in the later C3's. My battery sits on a fiberglass surface and I wouldn't trust some 56 year old f/g to hold the 35 pound battery down in a 2-4G accident. My passengers seat and the driver seat are bolted to fiberglass as are my lap style seat belts. All new seat belts are on the Christmas list for my baby.
