what do you mean by youre unsure what kind of car.
its gonna be a marina with a 1uz:incheek:
you dont have a lot of choice for doners as its either the ls400 or a soarer.both use the same running gear.theres no more choices
they come with independant front and rear on there own frames.
yes the front will be too wide but use there A arms and fab new brackets/crossmember.
the front crossmember on the car is alluminium and not really suitable for narrowing unless youre a pretty competant ally welder.
im guess ing that the marina is strut front end.sierra would work but then so would any car that had a strut front end,and rwd.may be worth looking ar bmw,s
again you may need to make a bracket/crossmember to take the lower control arm.
best go to a scrappy and start measuring once youve measured youre marina.
have to ask why the fook would you want to put something as out of date as a viva front end on youre car.
youre suposed to be upgrading with a v8 not going backwards.it isnt the 70,s/80,s anymore
strangly ive just cut a viva front end outa a car.
it will be down the local tip soon in its rightfull home.
