TRX250R 86 Chain roller and wire

I am unsure if the wire that supports the rear shock reservoir tube will fit the 87 model frame. However, though the wire will functionally work on all years it is definitely not designed for the 88-9. This early model style mounts through a hole in a bracket welded to the frame. The late model frames do not have this bracket.

The roller is in good condition. The bearing feels smooth and is functional.
