Hi
I don't know much about other countries VW bumper bracket styles, but in 1974 we got triangle front bumper grommet but still with same style rear bumper grommets as 68 and later bugs but still kept the same bumper bracket as earlier cars, in 75 we stayed with triangle front mount but went to the U shaped bumper bracket #9, we also got different rear bumper grommets #11
These newer bumper grommets #11 are very hard to get
