My 240Z is mostley stock. The package I bought was the Tokico ILK252 from JDMWorks13 on eBay. The box came factory sealed with 2 front BZ3015 struts and 2 rear BZ3016 struts. The springs have the number on them and I will retrieve that tonight.
When I inserted the BZ3016 strut into the strut housing (strut tube), the body of the strut (not the shaft) protruded about 1.5 inches. the only way that gland nut was going on was if I stretched it 1.5 inches! I searched this site and read half of what I found (which was a lot) but it focused mostly on the springs.
I carefully read all the material that came in the box and looked at the Tokico web site several times (tokicogasshocks.com) I finaly decided that if they were going to fit The spacer needed to be cut. Measuring everything, strut, strut tube, spacer, gland nut, I finaly decided to cut 1.3 inches from the spacer.
After, the strut fit perfect. The gland nut tightens against the strut body and there is a 1/10 inch gap before the gland nut bottoms.
So... what do people think?
