I have a 1995 16 with the integrated tracks. My jib traveler broke recently but no replacements seem to fit into the track!? I tried the new style with the brass wheels and the old style, all plastic car. Neither will fit! When I compared the new all plastic cars with the old broken one, the old ones seem to be thinner in the track (see picture).
The left is the old one, right is the new one. Note the thickness difference in the part that slides into the track. (not the width, but the "height")
Have there been any major changes to the cross bars in recent years?
why cant i replace my jib cars!?
