Good thinking although it's all boutique boutique farm shops down our way nowadays!Down your way pop along to a farm machine parts place, 663/664 [ way around terminals are only difference ] common on tractors and other farm machine's.
I use this one in three land rovers and the tractor. LINK
640SHD YUASA CARGO SUPER HEAVY DUTY BATTERY 12V 110AH YBX3642 - similar to @kermit_rr recomendation it has the terminals in the middle, but is a slightly lower rating so as long as the hankook physically fits I would go for that one.
