The battery terminals are a side mount and the battery is a 78 series. The bolts are 5/16'. The negative cable runs down to the side of the engine and is attached with a 9/16' or 14mm bolt. The positive cable runs down to the starter and is attached using a 15mm lock nut. This can sometimes be tricky to remove because the terminal stud on the starter solenoid can come loose while trying to loosen the lock nut. To prevent this from happening, hold the cable with your other hand while loosening the lock nut.
Hope this helps and good luck.
