[Closed] Marzocchi advice needed please!

Hello, I have a pair of 120mm 04 mx pro eta forks which I love but the bushes have gone, I also have a pair of 100mm mx pro forks without eta which are from 07 I think. What I would like to know is are the bottom legs on these forks the same? They look the same and measure in length the same but could I swap the top part of my forks and internals etc from my 04's to the bottom of the 07's? Or am I just being daft. cheers for any help and feel free to point and laugh if I am being a numpty, I just dont want to pay £80 to get the bushes changed!
