Hi - 73 911s, wondering if anyone's found the right solution for an AGM battery set for our early cars?

Thanks guys - hoping to not have to use any custom bracketry etc. Any old Miata battery? From certain years? Same size/format as original?

There isn't really a perfect option that fits OEM into the battery boxes that is AGM...(that I have found) I tried the Miata batteries (first gen IIRC) and I just didn't like how close the positive was to the body. There is a 'wheelchair' battery that supposedly fits really well, if you search on EarlyS registry you'll find it. I currently have the 911 size interstates in mine... seem to be working ok for now.

Best replacement are a pair of Sonnenchein gel batteries
