hi i know this might sound stupid but what is needed to fit a:
1) a gsi front bumper to a 1.6 sxi astra mark 4
2)a sri-turbo bumper to a 1.6 sxi astra mk4
as i remeber reading that the gsi bumper needs some extra part at the bottom????? or am i wrong and they just change straight over!!!!!
cheers for the help
