You can purchase the gearboxes from here

They do not have the rest of the drill though so you will have to figure out your own mounting assembally

You can also obtain parts off this site, but many appear to have delayed shipping.

All of the parts for the NBD are available. Try Black & Decker as they stock the exact replacement parts for the XPR unit. One issue is that all the part numbers may have changed, so be sure what you are ordering so you get exactly what you need. Point in case is the clam-shell. Still available, however the part number is different if the vendor has the new stock, old stock is still the same numbers. I found several (on the web) B & B service centers that had the parts with the old numbers.

You just have to surf a bit or take a trip to a local service center and make some friends.
