Where do these parts go?
 

I recieved my T Maxx lightweight race chassis a few days ago and it didn't include instructions. Assembly went together wine, but I cannot tell where the two peices of aluminum go. They are about .5" long, .25" diameter, with half of its length being a hex and the other half being round.

Got a picture of it?

Sounds like some sort of turnbuckle, or linkage?
