What are NHRA/IHRA requirements for battery hold down in the trunk? With the metal bulkhead I assume that I don't need additional containment such as a box, but just a means to keep the battery from moving, but am not clear on the requirements. I previously ran with battery in stock location so this wasn't an issue.

Thanks,
James

Any requirements on how to attach the bolts?

Chris,

Thanks for the response. Are there any specifics on how the bolts are to be attached through the floor? Do they have to have a specific size washer to keep from pulling through, or cross strapped, or welded?

Thanks for the info.

Everyone, thanks for the info.

This is a 1962 Fairlane so it is a unibody. However, the rear sub-rail goes under the area where I mounted the battery, so I made a U shaped bracket that goes under the rail, and then went with 3/8" all thread as ya'll suggested. I then made a top strap and bolted it down. The battery ain't going anywhere now.

Thanks again for all the help.

James
