Anyone mount battery UNDER, or flush in trunk?

727 & it was a good converter.... it happened about 17 mikes from home and I just kept driving it. The 727 innards, I’m sure, are toast. The converter, I’m not worried about. I can ride a bicycle down the road to Pro Torque converters. But I won’t... He he he he he
