Super hot Battery

Thanks again for all the replies and info. I think it best just to buy new one due to closer inspection the one side of the battery is slightly bulged so I think I'd rather not play around. Any suggestions short of NAPA for a decent battery for an original 65 GT?
Can I go up in years like for a 70's swinger etc. and still be OK?:book:

Yes, series 24 was used many years,
for example, a 1980 Dodge Aspen used a series 24 battery.
