Information around the location of front damper weld-on brackets on Lambretta forks is lacking so I've taken measurements from both my Italian GP250 and original DL200 forks. I can't vouch for the authenticity of either sets of forks as when you look at the dimples near the bracket these are in slightly different places. I would like to say the DL forks are original as the weld is neater.
The first measurement is from my DL and is taken from the top of the bracket.
The second pic shows this as almost 26cm.
This pic shows the distance from the bottom of the bracket which is approximately 23.5-24cm
Measuring from the bottom of the GP bracket ...
The LCBG workshop site (http://www.ilambretta.com/dampers.htmlmentions this measurement should be 10" (25.4cm) from the centre of the bracket to the same place I've measured!
So there you go, take your pick! A lot depends on what shocks your fitting and how you want them to look and work so the above is a starting point.
