67 Barracuda front brake drums, Alignments and tires

Look for a Kelsey Hays setup. They work nice and your wheels should bolt right up. Also if you have an 8 3/4 rear, you are good to go.
Reading over another thread, that setup has a bigger hub size than 2 3/8.
"The stock 73+ disks have a hub that’s about 2.6” to 2.7” in diameter"
I'm guessing thats the Kelsey Hays setup you are referring to.
