2008 Dodge Grand Caravan Sliding Door Cable Track Piece

So my Grand Caravan has all kinds of electric bits in the sliding doors. To feed those bits, there is a cable that fits in the bottom of the doorway. That cable is protected by a cable track, which follows it as the door is opened and lays down nicely and out of the way as the door is closed. Or it did, until the final link in the cable track broke and disappeared. Right now I can only find replacements for the entire assembly; cables, connectors and cable track. I am hoping to find a place where I can just get that broken piece. Pictured circled in red below.

I'll try the junkyards. One of the places nearby lists their inventory online. But they don't have this model in right now.

If you don't have any luck, try online for CNC machining supply.  Those cables are similar to the ones used in that industry.  The end piece/connector might be proprietary to the auto maker, but something similar may be found.  

I have had VERY GOOD experiences with this ebay seller

They are out of Nevada, and take apart cars. Nice folks, good used pieces. I highly recommend checking them.
