The original Koni shocks measured 13.625" eye to eye in the front and 17.5" in the rear. The front shocks do not have spherical bearings, they are captured rubber eyelets using a through bolt like most any stock shock, the rears had a spherical lower joint and a standard rubber upper mount. To adjust them you had to unscrew the top eyelet, remove the bump rubber, reinstall the eyelet and then compress them all the way to engage the valve, adjust the valve and then reinstall the bump rubber and eyelet, a very time consuming process. Later versions of the Koni had an adjustment window incorporated in the top eyelet like a Penske. I have a set of these purchased sometime in the late 1980's or early 1990's but never liked them because of the hysteresis vs Penske's. I have three way Penske's now and like them very much.
