I have a pair of Koni GP shocks I am selling
I listed the ad on a Swedish auction-site, it´s easy to buy on ebay but I have problem listing parts(maybe I'm stupid)..

Anyway, I cant find much info of these, only a commercial ad in Cycle World 1975:

Maybe someone have some more info?
length is 330mm eye to eye

I have a NOS set of these which are 343mm but cant get springs for them a the bodies are wider than std Konis. They did not come with springs.
I also have a sales brochure from 1975 for these shocks. They came in 308, 328, 343mm lengths. On the body is a part number that will start with 76V- If you tell me what it is I can provide some more information for you.

It is important that you do not try to compress these shocks without first taking them apart, replacing the oil, totally disassembling the piston and shaft and fitting a new modern top out rubber. Even on NOS shocks. The material they used for the top out rubber deteriorates and turns to sludge and easily blocks the tiny valving holes. if you try and compress the shock or use it, internal parts will be damaged. This is common and happens with all Konis. I pulled one of my NOS ones apart a few weeks ago and yep even though they have never been used the rebound rubber/plastic disc had turned to sludge and blocked up parts of the valving. I will be fitting new rebound rubbers that are ok with oil contact.

Also make sure you have the correct length bump stop and spacer/restrictor under bump stop (fitted on some models). If you have a too short bump stop, the shaft piston can bottom out internally and do serious damage.

That number means they are 328mm long, have normal damping (they did a hard damping version too)
and the application says they are for many models that use 328mm shocks. Bit much for me to type out right now but basically you can use them on any bike but you need to select the right spring to suit and adjust the damping internally. They are adjustable internally when you rotate the shaft and engage it with the foot valve. The buyer will know if they will suit his bike based on the 328mm length.
