what is all needed to update 83 front nose to a 86-87 front nose

[83BLACKHAWK]

I know I need a

84-87 header panel (is there any difference between 84-85 and 86-87)
84-87 grill


will my 83 front bumper work with the 86-87 header panel and grill

will my 83 front fillers work with the 86-87 header panel and grill or do i need 84-87 fillers

I heard my front head light lens brackets that go around the headlights will work with a 86-87 header panel or do I need them to

someone please if you have time, please let me know all i need to do this swap

here are pics of my car with my 83 front end,

I believe the header panel, grille, and the headlight bezels are different.

Header panels are the same, 84-87 Gn's don't have the ornament so no hole in the header like the T-Types
Grill, are all are the same size 84-87
87 in black trim
84-85 has some chrome, 86 I not sure if there is any chrome
your 83 looks the same

I think your car is so cool and unique as is with the 83 front.

The 83 header panel is totally different than the 84 and up models. 83 Bumper fillers are not going to work with the 84 and up. Headlamp doors/bezels are different between the 83 and 84-up. Bumpers are the same. Grills have chrome up to 87. 84 and 86 grills look alike. 85 has 3 vertical chrome bars on each side of the center chrome bar. I had to find and install all this on my 85 when I bought it as the original owner got hit and it was all taken off before me getting ahold it.
