Backhoe Mounting a BH90 Kubota onto a 2013 L series 5240 ( add on frame????? )

[Vandoman]

This winter I upgraded to a 5240 ( factory cab ) L-series, my wife suggested a backhoe as its the only add on I don't have...

Found a sweet deal on a used Kubota BH90 non PTO run unit... I already know I need to add on the alternative hydro system, the issue is finding the bolt on frame to mate the older (2009) back hoe to the brand new tractor.

Any suggestions, hate to not follow through on this deal.

Thanks
