I have also just replaced the grill on my FR. I also was having trouble with the last two clips on the side. I think the temperature (-5) contributed to the trouble, in that the plastic was brittle and my patience thin. Eventually i gave up, drop kicked the screwdrivers into the pond and pulled the grill out. Needless to say, i broke the clips/slots on the bumper but the new grill fits securely. I would advise to perform the transplant when its warmer!
