If you have a vented battery yes.
After fighting rust in the battery boxes on my 1970S and 1972T. I would buy an AGM, GEL or a sealed no maintenance battery before I would replace with a vented battery. Your car can use a group 48, 49, 94R It has different mounting holes in the plate for each.
Last replacement for my 2003 996 I went to an endurance Braille GRP 48 AGM. They also have GRP 49 both are expensive and straight bolt in replacements. I have been using AGM batteries for ~15 years. Currently in my BMW R1100RT and 1972 track car. The bike battery is still going strong after 9 years and the car batteries are still good after 12 years. YMMV
Braille Battery USA      Lighter • Stronger • Faster - B7548
Costco, Sears, Interstate, Porsche also have replacement flooded, lead acid, vented batteries for ~$79-$150 if that is the way you want to go.
Make sure to clean up the residue from the spill with baking soda/powder solution to neutralize the acid before it eats into the bulkhead under the battery tray.
