Anyone able to install the center caps on their FJ Cruiser 17" alloys with wheel spacers smaller than 2"? I know 2" will work. 1.5" should work on the front & I think 1.5" might work on the rear. 1.75" would work if I can find some. Best case scenario would be if the 1.5" will work (1.5" are readily available & I would prefer to use the smallest spacers necessary). Does anyone know for certain if 1.5" wheel spacers on the rear will allow the center caps to work to be installed?
