Thanks Bill and everyone - I bit the bullet and purchased the odyssey pc 925 as it was the only one that fits - made up a new alloy top bracket to match the original retaining bolts mounted the battery on its side and all good. The one thing I discovered with my research is that these AGM batteries require a charger that can run 25% of their AH rating in bulk charging mode to retain full capacity . So I may have to buy a bigger Ctek !
