Re: 65 mark 3 - rear shocks
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.

Re: 65 mark 3 - rear shocks
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.
