Well, I feel a bit stupid. I went down to the local autoparts store and asked if they had this battery. They had one in stock, but I didn't ask the price. When it was all said and done, it was about $205 before tax. I think it only has a year warranty.
Oh well. At least I have a battery now. Now just to fix the wheel bearing, the missing wheel wells, the windshield, the dash that doesn't light up at all, and I'll be set for at least for around town. Then later I can look into the HV battery, if it doesn't throw red triangles first, and the catalytic converter.
