Grille swap questions

agree with the correct forum comment mentioned above, but since I am here and also a D150 owner,,,
The exterior sheet metal, fenders, hood will interchange between a 86 and a 92, so the grill should also, you will need the 86 head light bezels with the 86 grill.
The 92 front bumper may or may not fit well with the 86 grill work.
