For 36mm TS 250 79-82 they would need to be 811-815mm long from axle hole to top of chrome. 78-79 SP370 are very similar, if not the same but I am not sure on the length of those. Also 80-84 DR/SP400/500S are also very similar at first glance but are 836mm long although 82-84 have air caps. I am considering a 811mm TS250 set as I would like some fork legs with good chrome, so I am considering them if they are the 811mm long type.
