I appreciate your response but I can be easily confused, so...

1) Would Group 78 with external box around battery likely fit under the factory swivel seat?

2) Would Group 78 with no external box around battery likely fit under the factory swivel seat?

Again, thank you.

Also, still looking for actual dimensions of clear space under the factory swivel seat.

When I asked the manufacturer they said they it could be installed on its side.

Yes, AGMs can be installed on their side but there is one thing to watch out for. Some batteries (not all) such as the Deka 8D that I have have tops that slightly overhang the sides and ends of the case. If these batteries are placed on their side the weight is not carried evenly but rather the weight is carried on the back edge of the case and the edge of the overhanging top. This causes undue stress on the edge of the top and easily causes failure of the top to case side joint. Two fixes are are easy. One is to install the battery on its side with the wider top edge overhanging the edge of the shelf so that the weight is carried evenly by the battery side. The other is to put some material such as a half inch of compressible insulation under the battery side with the top edge overhanging. This is the best as these batteries sometimes swell a tad in size so the side becomes very slightly uneven. The compressible material under keeps the weight evenly distributed rather than the weight being carried by the swollen areas centered at each internal cell.
