the stanza struts are really too long to use in a 1200, same with sunny ones
so when you lower the 1200 to a reasonable height you run out of suspention travel. even more so if you run camber tops
all you really need to do to run 200b or 180b struts is cut off the original spring perch, as its too big for the 1200 strut tower..then weld on a stanza or sunny spring perch, or cut the centre out of a 1200 one so it fits on the struts
the only reason stanza struts are really used in 1200s is that you dont have to change the spring perch....but when you have to cut the strut tube down to fit shorter inserts you soon realise its easier/cheaper to change a spring perch
ideal strut would be a 240z one, as they have the small spring perches short shocks and bigger brakes than that rest of the datsuns of that time...pity its so hard to find them
i run 200b struts in my car, its rather low in the front and has camber tops (sit the car higher than what stock strut tops do so even less travel) but it still doesnt bottom out, unless the cars loaded up with people going round a corner then hitting a bump
