I fitted some Austin Healey Sprite rear bumperettes on the front of my Plus 4 2011 car, got them from AH Spares, they're about £50 each plus vat. I decided i preffered the full bumper look and went back to full bumpers. Fitting was'nt too difficult, bit of bracket fabbing, fitting to rear i guess would be similar. I still bave a new set of 4 if you're interested
