shaft length

[hotrod]

So I just bought these off fleebay but the seller wasn't sure what they were and only said he bought them as conversion shafts. Does anyone know what length the proper shafts should be so I can check them when they come. Also what's peoples thoughts from the pic?

pics don't work so can't tell what you have if they are equal length the measurements are in there.

There's no mention in the thread about the long non equal length shaft. Does anyone know the size if that one please?
