seems as your running TRX rims, might as well go to the bigger struts

so first on your list of things to buy would be

late ute,late 120y stanza or sunny control arms
stanza or sunny steering arms
stanza or sunny balljoints
stanza or sunny tierod and outer tierod end
late ute or late 120y castor rods

then you can bolt most of the bigger datsun struts straight in, such as the 240k struts you have for sale
so that $700 covers all the suspention stuff too i guess?
and are you planning on doing anything to the rear brakes?
