New bumpers

Looking to get new front and rear Black bumpers for my recently acquired 1.5gx.

Due to other commitments the short chrome bumpers are sadly out of reach at the moment. The current bumpers are far too faded.

Any idea where I could get a new set? Has anyone purchased euro car part ones?? 

You could try a heat gun to get the bumpers back to black then you need to seal them with a bumper conditioner. Don't get the heat gun to close or the bumper will melt. There might be a guide on here about doing it, there is some video's on you tube

GX bumpers aren't black. they are grey. as are the arch spats. the mirrors are black though.
this stuff works well and last 5 years easy, there is enough in the tube to do the bumpers twice, still using up the pot I bought 7 years ago.
