Exposed threads is what you want. If the nut bottoms out without tightening against the strut the strut would be loose in the tube. What you don't want is the gland nut hanging on by 1 or 2 threads, which is the way the original picture looked to me.

When I replaced the struts on my 240Z, Tokico specified that about 1/8" of threads should show. Mine bottomed out using the provided shims. I went to the local hardware store and bought extra spacers that fit well with clearance for the strut rod. It all worked great. If you have enough engaged threads that you feel it is solidly engaged, just go with it and be confident it is correct.

here's whatt i sent to KYB;

Subject: Strut install

I purchased 361002/361001 struts for my 1971 Datsun 240z. Installed

361002 front struts, tightened gland nut to proper torque. I found that

I still had about 1/4-3/8" exposed threads on the gland nut between the nut and top of strut tube. The nut will not bottom out on the tube. I also

know of at least 3 other car club members who have run into the same

thing.

Is this acceptable and normal for this application?

Thanks,

KYB's reply;

Our nut will not bottom out like the oems.

Our nut will use 3/4 of the threads on this model

i didn't get 3/4 of the threads, but i am comfortable with it based on the feedback from the guys here.

thanks all,

bart

they look fine, my Tokico Illuminas did the same thing, they required stupid spacers.... but it works fine. no oil leaking or anything.

hopefully installing my new tokico hp's and springs (1") this weekend in my 77, if the idiot paint dude gets done screwing around. Made him repaint the front clip for the 5th time.
