Group 31s usually run $500 each.
Looks like you'll have to turn a hose loose on the inside of that find.
I'm a firm believer that not all battery brands are the same quality and priced accordingly. Idon't know where you're getting yours that they're $500. I paid $113ea for 2 group 31-5T batteries from O'Reilly's, some found Walmart batteries in the $85 range.
Most pics I see of the inside dashes on buses at most auctions look as though the left the doors open during a dust storm, this one is no different.
