What "makes" a 66 Barracuda a Formula S ??

Do the 10 inch drums fit in 13 inch wheels? I have my 273 4BBl, 4Spd in storage (and have not driven it since 1987) but will check the measurements when I pull the tires for some repairs (currently soaking the cylinders to try to get it started after all this time ) . In the dim recesses of my memory my dad said the discs and the bigger drums did not come on 13 inch wheel cars, so i just thought we had the 9 inch drums.

The '65-up 13" wheels will fit the 10" drum brakes. The '64 and earlier wheels won't due to a different center hub design. You can tell the difference between the two by the size if the slots between the rim and hub. Real thin slots work, wide slots don't. Factory Kelsey Hayes disc brakes need 14" wheels. The 14 X 5.5 wheels fit fine. Some 14 X 4.5 fit too, but, not all.
