Center caps... Need some help

[buickfunnycar.com]

Hi Jay, tried to give you a call back but got your voice mail. I just do pulled both caps from the VWW and a TTII and the TTII cap bolt pattern is larger than the VVW cap. So hope this helps.

Yes they are different as Tim has confirmed.
I got mine through Tom Cruise at the Mustang Ranch here in Nor Cal because like Scott Drake who specializes in Mustang stuff,they are made to fit the Fords.I know VWW now sells them as well.
