Hi,

I'm in need some insight. I'm stuck matching rims, center caps, and lug nuts and I can't find the info I need anywhere online.

I've purchased and installed new OEM aluminum rims on my '96 E350. The rims are F5TA-1007-JA7700 (late 90's F350 stock).

I've also purchased Ford OEM center caps (F5TZ-1130-J) but I can't get them to fit over my lug nuts. (my lugs are 7/8" hex head. 9/16-18 thread)

My question is this: what lug nuts do I need to buy?

Thanks for any help you can offer.

 

That's weird. I had those same Alcoas on an F250 years ago. No issues clearing lug nuts. I know there are larger than 7/8 lug nuts on some of the trucks that still are 9/16-18 thread. But mine were the 7/8 also.
