lol!
Year the rear will have a standard mk2 spoiler, flushed boot with a modified VW boot opener (the badge that lifts up) - replaced with an Opel badge - detailing either side this will reflect the chrome bar across the front. Am about to start on the rear bumper but 1st need to do a bit of work on a couple of models... See page 7 of thread for basic design of rear...
As for lights will be making my own similar to these but using those from a landrover!

They will be recessed though
