Are you sure that it'll fit the '79-'82 front end and cowl grill? The '79-'82 hoods are different than the '83-'84 and the '85-'86 style hoods. Also, the body lines on the '79-'82 hoods match up with the cowl grill and nose pieces of the '79-'82's, both of which are different than the later model units.
I know that your hood will bolt on but it may not match the body lines.
