I also just did this recently.
My recommendation is to ground your battery to a chassis point in the trunk. Use a grinder to get the paint off the metal for a decent ground. You don't need to run a ground all the way back up the side of the car.
Also... make sure you keep the engine block ground wire connected like it is. It should be grounded to the chassis somewhere near the battery tray. You need to keep the block grounded out.
