i have just bought a ph2 172 and this weekend i decided i was going to take it apart and give it a good clean but when it came to removing the front bumper i removed all the screws and bolts that i thought would release it but it wouldnt come off. could anyone tell me if i was missing anything? Also i have fitted the origional rs upper grill after purchasing the car with terrible ktec metal grilles but it doesnt fit properly. It will clip to the bonnet but when you line it up with the holes in the slam panel to clip it in place, it pops off the bumper like the bumper needs to be pushed further in but nothing else looks out of place. It had the ktec lower grill also which i have replaced with a stanard and it also doesnt fix in on its clips on one side can any body help?
