hi guys, does anyone know if a 1000 2 door sedan rear seat will fit a 1000 coupe?

No it wont.

would there be allot of modification or are they completely different, as i and a 2 door sedan leather interior and am thinking about using it in a couple ie: the one on ebay at the moment if it doesnt get bid up too high

I guess you could recover the coupe rear seat using the leather from the 2 door seat , should work fine.

has anyone got a pic of a coupe rear seat that i can see the similarities to see if the leater will adapt easy enough?

coupe and 2 door ? I really cant see it working as i understand it the two door has the fixed rear seat like the 4door sedan.
the coupe's have a folding read seat alot like the wagons.
I had a look and the seat from the 4 door looks a bit taller than the coupe.

if your keen to pull apart a seat I guess it's cheaper than getting one recovered
