RF receiver installation

Hi all,

So i've finally got my new RF receiver for my P38, but i can't get the bloody spring clips off the panel by the rear quarter glass. Any tips??

1 other question - I've noticed that some times when i start up and engage "D", nothing happens i.e. the car doesn't move, and doesn't react when i press the accelerator....then all of a sudden it jumps forward. What's that all about?

Thanks,

Alex
