READ FIRST: We ONLY HAVE ONE, NOT A PAIR This strut is stamped "81661" ( and in small letters also "N350M1") We know little else about it. A web search brought up this exchange list below, however, please study pictures to be sure it is what you need. Also note does not have the 3 stud bolts on top of spring plate, so you will need to hammer out your old stud bolts from your old strut, and hammer into this. ( Thread a nut on top before hammering so you do not damage your threads. or use a press) This is new but we think it was a store display. There are 4 small tack weld spots on bottom where it originally was attached to a display stand .
