The Group 27 was too big. The proper battery on my 88 Spur is a 34. The AC Delco gold has 750 CCA, 875 CA, and 70 AH. That was the best I could find.
BTW, the car comes with a 1" "platform" to mount to the bottom of the 34 to give it the proper height. The box that holds the battery is bigger than the battery. It is an odd trapezoid shape with one right angle. The strap down bracket that goes on top of the battery fits the 34 perfectly.
