I am trying to remember, but I do recall the internal construction is quite simple.

I placed a thick nylon cable tie around adjacent spring loops and then repeated the cable tie around two more loops but 90 degrees offset over and I've again. I cinched them up sequentially in the same sort of pattern. At some point I think three ball bearings fell out and the sticks came apart easily.

I had my springs re-chromed and just cleaned up the internal shock parts if I recall correctly.

I have a basketcase Mark3 too- I can send you a drawing of the missing frame lugs if you need to get them made.

oh and here is a picture or 2 of a spring compressor from a guy in UK.. bought it on ebay but its too short for Ducati springs so he is building a new version for me that is longer .. i will post pics and the link to him once i get the new tool and it works..

Dave,
Let me know if you want an actual drawing, but it probably won't be needed, at least for the exhaust/buddypeg lug I noticed. It's 20mm diameter, 25mm long, with a 7/16"x20 tpi thread. I've never heard a good explanation of why Ducati chose this thread pitch, but it's found on the bevel twins also. If you made the lugs from 3/4" shaft I doubt if anyone will notice the lugs are 0.037" undersize.
