I don't know if anyone can use these on their 1974 to 1981 Firebird but hopefully someone can, otherwise I'll scrap them.
They are 547048 and 547049, 1-1/8" cores: one came off a 1975 Firebird and the other was a rebuild that was on the 72 T/A when I bought the car.
Looks like the dates are "D64" and "D47"
$10 each plus shipping.
