Stanza struts dont bolt in, they need stanza/sunny lower arms/balljoints/steeringarms and outer tie rods and radius rods. Same applys for all other datsun struts, BUT early 120y and 1200 struts are direct swaps.

I personally dont like stanza struts as they are very long, they bottom out all the time on the road without shortening them.

SO

If your perpared to shorten a strut then swapping spring perches shouldnt be a problem (damn sight easier if you ask me) so you may as well use something with larger brakes say 280zx or bluebird, these struts dont need shortening just use a 1200 spring perch and lower arms etc. as above.

Have a look at my stuff on the weekend when I give you the motor and parts matt!
