1982 mk1 tintop gti

Hi everyone. Just bought a mk1 tintop that needs a bit of work and some parts. It currently has a kamei x1 kit on but looking at returning it to original.
  some of the parts needed.
1,tailgate
2,both front wings
3,wiring and plug for the ignition behind the barrel
4,front grille and lights
5,rear lower valance
6,both outer sills

 probably a lot more bits will be needed as i get deeper in,any help or info on where i can get these parts from would be good.

Thanks Lee

Im sure I have a new rear panel in the garage.
If I still have it you can have it for £20 plus postage.

Cheers,where are you. Postage would be to bl2 2rp Bolton,would you be able to get a price for postage? Cheers
