You can change the 630 over to the old style hookups for $700 if it isn't already. Looks like $500 for the new feederhouse hooks and facia and $390 for the 10 series controls and harness. Our dealership stopped messing with the wedge kit a couple years ago. I don't think it's even possible to convert a combine older than the 50 series to single point hookup. When we did our 9650 it cost $1500.

A lot of the parts can be found here  www.lankota.com  cheaper than through Deere. Good quality stuff.
