I have a 1978 two tone L-82,4 speed, A/C and loaded with options. My question is , I am not the original owner but I have the window sticker and need to know what size battery came with the car. The choices are 87-5(430 cca) or a 89-5 (465 cca). This is not the Pace Car, which came with the larger battery, and the window sticker does not show the UA1 HD battery option. Does the L-82 or A/C include the HD battery in that option package? Tnx, John
