IF the shocks came off of a 5 or 6 series vehicle, they have the plastic caps with the larger opening, and will use M3 metric screws, and 91445 (plastic) top shock bushings (or aluminum sized equivalent), and M3 screw in lower pivot ball ... ... if you are unsure of which you have coming, post a pic and I can probably tell you

Edit to add: .. forgot to respond to your 91815/6/7 question ... these would fit the 5 and 6 series shock caps, too large diameter for the 4/SC10 series caps ... should you need aluminum bushings for your shocks, I have several sets that fit 5/6 series caps that I could let go ... probably a variety of standoffs as well
