Same fit, same part no. for 7 and 9 on the Boge. The gland nut usually does Not go all the way into the strut tube, the top lip of the nut almost always if not always, sits several mm above the top of the tube.
Car sits higher, well all or almost all gas shocks do press up on the chassis; Bil HD makes an obvious difference for example so early on there may be some height difference, but over time that will change.
