Need information on radiator support for 1980 c10

[SuperrOscar]

I bought my first ever truck and i'm trying to figure out if a 1973-1974 c10 radiator support will fit in a 1980 c10. the reason i'm trying to do that is because the radiator support that i have right now is rusted and i also want to put a 1973-1974 c10 grille on the 1980. Thank you!

It wont.
The core support is different but then again 1980 was a bastard year..it still wont fit..those grills are super cool..ive got a 74 that I couldnt fit on my 75..

Whats your backup plan? Cuz this one aint gonna work im afraid.

the 1980 core support differs based on headlight design. round or square eye?

if round eye, its a match but with extra holes and cutouts on the 1980, im not sure what all 100% those holes are for, but they are the small cutouts all over. not many different ones.

UP till recently, LMC listed 74-80 as one #, 81+ another. now the 1980 one is its own IF round eye. probably a slight mfg change that can be easily made but for sake of accuracy thing.

No. For real! You ought see this xxxtra clean assed 74 truck grille I have.

P.O.s were trying to put it on the 75 I had and gave it to me with the sale.

I ought list it on eBay...it's sooooo perfect!

Right now it's hanging on my kitchen wall lol...appreciating.

LMC shows 73-74, 75-79, and 80 as three different part numbers.

my bad, didnt see the 73-74 only one or remember that it was special.
based on photo, id say differences would be emissions / aux cooling accomodation, they should bolt in place of eachother.
