I just finished putting R31 inserts into sectioned stanza struts. I can confirm that all the different R31 gland nuts (holds insert in) did not fit the stanza tubes. I had a nut from my R31 struts, a fine thread nut and a large thread nut that came with the new shocks and all were too big. I used the stanza ones I had but thought it was interesting that they were all different.

I have lowered the stanza spring perch so it is level with a stock rim (about 10mm clearance). Obviously this isn't enough for the stock stanza spring so I also cut them by 70mm. I put a flat on the R31 insert thread so it fits the stanza top and also machined a bush so the step down is the right size for the bearing seal.

But I now remember reading somewhere that I had to use 1200 strut tops. Apart from the top three studs being bigger are there any other differences that stop me from using the stanza tops that I've just put together?

Just trying to have everything ready so I can do the strut/brake swap fairly quickly while I'm at work Thursday (got no work on but still being paid to stick around encase I get called out).
