"U" Barrel Tracks for ROTJ E-11

Replica "U" barrel tracks for ROTJ E-11.  There are 7 of them with varying lengths which should all line up together towards the back of the barrel except the 2 lower pieces.  The tracks are 1.5 mm thick through the "U" & the bottom of the tracks has a 1.562" (39.7 mm) diameter arc on it so that it will sit firmly against the barrel.  The holes are spaced to go between the holes in the barrel so they vary every other piece.  They are tagged together which will have to be cut apart.  There are holes & counterbores to accept a 4-48 screw to be able to screw to the barrel.  May not work with other kits or pieces.
