Help with ID of front grille needed for my replacement Cab

[paladn]

Hey all,

Im new here so please forgive me if i have posted in the wrong place.

I have a 1979 K30 Dually crewcab that the cab is almost completely rusted out on.

I have purchased a 1987 crew cab to replace it.

However there is no front grille.

Can someone help me ID this cab as parts for these are not easy to get in australia i dont want to buy something i cant return.

I  have attached photos

Any help would be great.

To me it almost looks like someone has done a 89-91 front clip conversion to an 86 body but im not sure

You are correct about the 89-91 Conversion

You are correct about the 89-91 Conversion

     You will need to get the grill for the 89 - 91

Are there a few different types of grilles for the 89-91? It looks like you can buy a single price in plastic or an alloy center but I can't find the light surrounds for it

Yes there are 2 different.  One is for the Silverado (the one that goes with your headlights)  The other is for the Custom Deluxe, which is the base model with the single headlights
