Challenger 65 track

[Carl billings]

Have a track on my 1990 challenger 65 split quite bad, other side worn but no splits, looking for a used track to just replace the split one if I can find one.
And help would be much appreciated

I have sourced one good 25" genuine cat track, still on the lookout for one more for the other side, low tread doesn't matter as long as casing is good
