Which bolt pattern?

I'm going to put discs on the front of my 65 cuda, /6, and keep the drums in the back. Which bolt pattern would be better for selection of rims, would like to go to 15". All opinions and suggestions are appreciated.

There's absolutely no doubt that the newer 4.5" bolt circle gives you a better selection. This bolt pattern was and still is used on a number of cars, including the larger body Mopars, as well as 73/ later disk brake equipped A bodies, most Ford pass. cars, Dodge 2wd pickups, Studebakers, Rambler/ AMC cars, I don't know what all. LOTS of vehicles used this pattern.

Thanks for the confirmation. looks like I'll change the rear end also. Aprreciate all the good guidance

I just bought a 1972 Scamp...previous owner found an after market racing disc Brake set-up wich actually kept the original small 5 on 4" bolt circle. There are still several rim choices for 14" and 15" sbp rims including craigers, centerline and Americans. The choices were better for the 15" rims and you'll find more tire size options as well. BF Goodrich still has a lot of choices for 'A" body tire combos.
Try to keep real.
