OK glad to know that. Yes-they didn't have a 35 in stock so I bought the 25 which had the correct orientation. And it fit perfectly in the slot.
Blas, I neutralized the spilled acid in the compartment with baking soda / water solution and it made streaks everywhere. Can I now rinse with plain water? I hate that it rusted the fenderwell but the converter stopped that. I'd like to clean it all and repaint after the new one goes in.

And Fred, your source may be right but I'm mystified why it was perfect for 2 years and suddenly the plates shift or sulfate and causes fluid boil over. But it still runs the car and reads 12.6V.??
