The post was the wrong type even though it was a top terminal battery and the size was totally wrong, the CCAmps was 330 the original was 500.
I use this kind of battery in my motorcycles and cars I like the power and life of this type of battery, the only way to use the battery in this car would be to install it on the side and the clamp type wire mounts would have to be on the left as facing the car this being the pos post and neg on the right.
I modified my Shelbys battery tray to use this type of battery it’s a plastic base so no harm to the car.
Maybe later I’ll see if I can find one that will work in the car I’d rather use a better battery for the car.
