Need coupe GT information.....lots..lol

[Jason someone]

well I'm replaceing teh rear drum brake assembly with that of an audi 80/90 
to upgrade to rear discs.

I know that the rear struts are a tad different from the 80 then on my coupe 
so I'll have to use them as well.

my question is this:  is there any benefit to running the full front set up 
from the audi80/90 on my coupe gt like are the discs/calipers any bigger for 
it then what I currently have or would it not even work anyways??

my question wouldn't be that difficult if I could find decently cheap strut 
assemblies for my coupe and not for teh 2wd 80/90's.

and also other then Euro lights what are my options for better lighting on 
my car?  will audi 80/90 lights work or do they require a lot of modifying 
to make work???

anyways I think thats about it for now.....I'm sure I'll have more questions 
later  :-)

and thanks again in advance for ANY help as it will help me in rebuilding 
this little beast.
