65 barracuda drum size

Im not planning on using these drums i just want to know if i have 10 inch spindles so i can buy wilwood disc conversion.
Be aware that the Wilwood hub is larger, and many factory wheels won't fit. There's several threads on the forum you can research that detail this. As long as you know what you're getting going in, you can plan for a satisfactory outcome. Several people have made the purchase and found out the hard way they needed new wheels.
Good luck!
