Looks to be the right part. But, they aren't technically "correct" for the 1980 trucks as these are E1TZ 1130-A's, which came out in '81 and in '80 they were still using D9TZ 1130-A's. However, the E1's replaced the D9's in '81.
I can't tell you what the difference is between them, but it must not have been cosmetic as Ford still used the combo of B on the front and A on the rear of 4wd vehicles through at least '86.
And, did you know that these wheel covers existed? Medium Blue and Fawn? They are shown for E-Series as well as F150's from 1982 - 86.
