I have a jdm gd1 (here in australia all jdm untill the gd3's) soooo my front grill has the 2 screws holding it on directly behind the mesh. attachment looks like this:

JDM 01 05 Honda FIT Jazz GD1 GD3 Mugen Front Grill Grille OEM | eBay

however, would this type fit?

Front Grill Grille Black Honda Jazz FIT GD3 04 07 | eBay

its got the 2 funny tab things on each corner, which doesn't look promising :S

cheers
Maty!

 

Not a direct drop in swap but the newer one PROBABLY can be modified to take the old style screws. Depends on your skills if you can do it.
