Hi All,
Will both seats are now out and I'm well on the way to removing the carpet. Considering how much water was in the foot well every thing is look ok under there. The passenger seat runner is bit rusty but should clean up ok.
Now the Elan is a bit cleaner I can see where some of the wet stuff is getting in. Can anyone point me at a diagram of the roof? then I can identify the seals that I need. Being new to the Elan scene I have no idea what seal is what, the one that "goes over the whatsit and down the thingy" wont get me what I need. Any info on suppliers would be good too.
You can see the rust stain from the seat runner
The muck does come off and the carpet and it's in surprisingly good condition.
Thanks for your help Jon.

that the above is a top tip.
