doing up the magna and wondering if anyone knows wheres i can get a custom chrome grill for it?

Have a look at verada grilles, theyrre chrome?

Some verada grilles have chrome surrounds. If you want chrome in the inner part, that is from a KH.

Thats a boot garnish, not a grill!!

I bought a new TE/KE/TF/KF chrome grill from my local Mitsu dealer back around 2001, cost around $120 IIRC.
Maybe Mitsu dealers can still get them, maybe not.
Price may have gone up a bit since 2001 though!
