This is an aluminum grille insert for all 1929-1930 Chevrolet cars & trucks. These vehicles originally did not have a grille insert. This is for Street Rod applications only. THIS INSERT REQUIRES 1/2" OF SPACE from the backside of the grille shell to the front side of the radiator or condenser. It comes with brackets for mounting. Finally, a great alternative to the laser-cut street rod grilles! These new aluminum street rod grille inserts are available in two different finishes and two different bar widths. 3/8" spacing on grille bars is a more original look while the 1/4" spacing is more of a updated hot rod look. With the tighter 1/4" spacing, the radiator, fan and condenser are more hidden from view, while reducing air flow by only 7%. Finish options are: Front Face Polishing; Full Polishing – Front & Sides. Choose the finish option you prefer. Choose the grille bar spacing you prefer. Get ready to have a great looking old Chevy! Grille inserts are available in four different configurations.
