1969 Race Dart w/ 426 Hemi- garaged for 45+ years

What was the typical skinny front tire size? I will check the rears when we pull them and replace with similar size DOT race tire.
I am running a 155-80/R15 BF Goodrich on mine but that is pretty short. It helps with my fenderwell headers though. Many of the front runner tires are tall, they just didn't work for me.

rears I have Hoosier Quick Time Pro 17125QT. 295-60D15
