Hi Bill, Just to clarify. 1970 grilles will not fit on 1967-1972 F250s??
Thanks!

 

'70 inserts' mounting points are specific to the '70 shell's tabs.

Swapping to a 70 grill requires the inserts and shell as an assembly. 70-72 headlight doors and gravel shield are interchangeable.

 

And there are two different types of grille inserts and frames. Early 1970's have right and left specific inserts, the tabs for the left insert are located in a different position within the frame.

Late 1970's have the same inserts left and right (they're actually both right sides), so one cannot install an early left insert into a late 1970's grille frame.

When Ford made this change they supplied the grille inserts with the grille frame as an assembly (D0TZ-8200-D - you bought one a these recently). But the inserts could be bought by themselves.
