Will ae86 stock springs fit TE71 liftback ?

Well actually what concerns me most is to do maintenance now on the car and i do not know anything about what type of oils i should use it got T50 transmission so that is easy in the engine i put some 10w40 spec oil but the diferential is complicated because i do not know how much oil it takes and if i need LSD oil or it can be jast normal 80w90 GL5 oil.
So i must just guess what i should out in. Also i will look at it more this week because a problem appeared with gauge that is not showing engine temperature so i hope it will be easy to find the cause for this.

Including the picture of repaired car there was not broken spring at the front but the spring holder was rusty (gone) and spring just fall trought it.
