body part swap

[dbcox]

i got a 1980 2wd chevy. I want to change the front out to the 89-90 dual headlights like a blazer. I know it can be done on 81 ithink and up to 87.
My question is since everything on this one needs replacing, if i buy parts for say an 86 will it work on the 80? If i get the new hood, new cowl, hood hinges, inner fenders and fenders will all that match up so i can order the parts for the grill swap? radiator support will of course be for the blazer, looks like the 89 crew cab grill was the same as the blazers too. thanks
