Prodrive front splitter for bugeye WRX (fitting)
 

I have one of these ready to go on, are they literally stuck on, I bought it second hand, and needed repairing, so it has been done and painted. there is a long part on the bottom that looks like it fastens to the underneath, but what to do about the front and sides?

It looked like it was stuck before as there was some adhesive left on it.

Any ideas guys :)
