Kubota BT 751 backhoe control valve repair

[Tom Taylor]

Does anyone have a source for a rebuild kit, seals and o-rings, for a BT 751 backhoe control valve? the part Number for the valve is 75592-63010. I can find the individual parts but they are pricey and was wondering if there is a kit available to rebuild the valve. Or even a rebuilt valve at a reasonable price? thanks in advance
