So im changing the struts on my 93 245. Things went pretty smooth until I began installing the new struts. First I assume the struts I removed were the oem/stock struts, they had volvo stamped on them and came with the (I assume original) gland nut. I removed the old strut and replaced it with a Boge/Sachs touring strut, which came with replacement gland nuts. Side by side the new/old struts look almost identical. The main difference between the two is in the gland nut. The new one looks cheap, crappy, 2 pieces welded together, and had about half of the threads as the original. The old gland nut looks like its made out of a better grade steel is one solid piece and is still 100% reusable. This brings me to one of my problems.. neither of the gland nuts will seat fully when torqued on the new strut. No there is not a spacer in the strut. Yes I am sure. So here are my questions,

1. Which gland nut should I use, the only reason I have reservations about using the old one is the paperwork that came with the strut said to make sure to use the nut that came with it. (even though it looks like garbage and the other one fits the same if not better)

2. Should I use washers to space out the distance between the strut body and the gland nut? Basically, if I leave it be, will it cause the gland nut to back out and cause the dreaded strut clunk.

Im Driving around my parts volvo while I figure out what to do with these Gland nuts.. any help/strut wisdom would be appreciated
