what are the bolt pattern for a 66 coupe? i wanna say 5x4.5?

and whats the bolt pattern for a 85 bronco 9in?? i think its slightly bigger?

 

the 66 mustang is 5x4.5" alright. I have no idea what the bronco is though.
Why ? did you like some broncos wheels?

 

full size broncos use f150 bolt patterns

 

The Bronco should be 5X5.5. My son just purchased a 9 inch from a F150 for his 1938 Ch&vy.
It has 5X5.5 and 31 spline axles. Not a bad find considering the engine trans combo he plans on running. Stroked 454 CID with a turbo 400.

The only issue is that the rears now do not mach the front lug pattern of the subframe we installed.

 

yeah, i was wondering becuse i picked up a 9in out of said bronco and was just wondering if the bolt patters were different cause idont really wanna buy new axles until i have to... ill prob pick up the same wheel with differnt patters
