Hello,I am hoping somebody will be nice enough to give me the measurement that I am looking for.I have a set of 16inch Alcoa dually wheels(they are not factory Ford)I need the width notches edge to edge so that I can machine my wheels to accept the factory ford center caps.

WHY!?!?!? they suck. Use Alcoa push thru caps, you will be MUCH happier

 

Because........The wheels are going on my 79 F350 crew cab,push through caps will not work,alcoa lugs and caps will not work(I also do not like them) because I am using mag lug nuts and the wheels center on the lug nuts,I like the factory Ford center caps ect......And I posted this question in this section because the people of this section own trucks that came factory with these wheels.
I just want a measurement.

Good luck. I am curious why you THINK the push thru caps will not work

 

Can you post a picture of what you're after, OP?
Having a hard time picturing what you're looking for.

 

All I am looking for is the distance .

 

I'm getting just right under 5.5" - someone else may chime in with a calipered result.

 

Sorry, no factory dually wheel here, just SRW

 

Thank you,I can work with that.
Chris

 

They also have a concave shape to them to hold the tab.
