those of you with battery in trunk

i need opinions on how to mount the thing. car is a 93 coupe, i got the summit racing relocation kit, and got a dmaller box, since i dont need the huge one that comes with the kit. i've got a group 24 box, with the appropriate battery inside it, but i was wondering how everyone is fastening the whole assembly down. i've got the cross bar that goes over the bat., and the hook brackets that clip over it, but there's no way to fit the j-bolts between the bat. and the box. what do i do?

get long threaded rod from home depot. You will have to drill through the trunk floor and fasten the rod under the car with a locking nut. You may have to lower the gas tank too.

got the same problem with the summit box. Looks like I'm going to have to get a custom box.

When I bought my car, the original owner had welded threaded rod to the trunk floor and they came up along the outside of the box. He ran the neg cable directly to one of the rods. It worked, but wasn't the best looking setup. I ditched it all and went with a Taylor box and drilled through the floor. Dropped the tank and bolted everything down snug near the cross brace that runs in front of the gas tank.

summit doesnt exactly supply instructions with their crap. all i got was a template for the holes, but since im not using that 500sq. foot box they send, the template doesnt help me much.

the one thing i was thinking, was running the rod through the floor, as stated, and cutting a slot in the box for that little tab/hook thing to go through. then just run the j-bolt through that. only problem there is that once it's mounted, there's really no way to get the battery out. not without dropping the tank to get to the nuts again.

I hated to go under the car every time I need to remove a battery. So I welded 2 short square rails (perpendicular to the car axis) to the trunk floor (which required lowering fuel tank to protect it) and bolted my Summit box to those rails. This elevated the box by 1.5". Then I took 2 steel bars with holes on both ends, put one under the battery box, put another over the battery, ran threaded rods through them and through box floor and they work as clamp downs.
This may not be the most elegant solution, but it works very well.
Summit instructions made me laugh.
