B6200 FEL control valve

[B6200]

I was just wondering if anyone out there has rebuilt a FEL control valve on a kubota 1640 Loader. It was manufactured by Danfoss and it still works but is leaking by to resevoir. I have the the rebuild kit and debating on rebuilding it or buying a new valve. I have owned the tractor 18 years and it has 900 hrs on it. I have rebuilt the hydraulic cylinders. Made over size pins for the bucket and reamed the holes to fit. The bucket is tight and the control valve would finish the job. Any thoughts would be appreciated.
