Physically they will fit but are a pretty different shape than what your car actually calls for.

You have a series 2 body while the 1/4'rs you're looking at are for a series 3 body. (actually one of the sellers is a bit confused too as the one labelled '83-94' would go into series 4 and thus couldn't fit those years as again it's a different shape than the S2 or S3)

 

Many thanks Tifosi, the pictures make it clear to me now!
Any idea where i can get replacment panels from?

 

Actually there are several places that patch panels and outright replacement panels can be had.

Somewhere up near the top of the forum is a thread with a whole heap of parts suppliers listed in it, but right off, I'd imagine Centerline, IAP, Alfaholics, and classicalfa would all have something available.

EDIT:

This thread is the one I meant.
