Questions...suspension on 86 cgt

[Jason someone]

basic question...
Can i use the suspension from a later audi 80/90 Non-quattro on my 1986 audi 
Coupe Gt non quattro
are they the same mounting points?  I realize that the 809/90 parts are a 
bit on the "taller" side and may raise the car slightly.
any BTDT's about this?

just looking to know if it will all bolt up without serious modification

looking to run a set of FK budget strut/spring combo's and would like the 
audi 80/90 parts

thanks to all!!!
