O.K I've decided to stick to the plan of putting the battery in the trunk but have another question. What is the best way to get it to the starter, I layed under the car for quite a while "it's tight under there". The only place I see that you can bring it threw and keep it somewhat away from the headers is from the frame rail right between the opening in the headers. Running it up the tranny and then up gets it pretty close and there is the shifter linkage, trans coolant lines, etc. Then there's the torsion bar crossmember (looks like either under or threw it which means drilling holes). Hopefully 65 Hemi see's this his battery installation looked great. Thanks
