Help with part name?

[erich weaver]

The shaped plastic part that guides the aft end of the canopy along the track on my -7A slider appears to be cracked and I want to replace it. Can someone help with the name of this part? I am NOT talking about the plastic blocks on either side of the the fuselage, but rather the single plastic part that supports the rear of the canopy as it slides forward and backward.
thanks
