I really have no personal knowledge about the 2122 468 wheels, but for some reason it comes to mind, and the fact that they are list for "drag racing and rally" brings to mind the "mostly" 66 rally efforts by Scott (drawing a blank on the last name), which was a factory backed effort, and with me having a 66 Formula S (this was around 67) of course I felt the kinship!

I do remember looking at some of the things listed in the Direct Connection or was it Hustle stuff? catalog and think there were wider, 5"x4" pattern wheels listed, this would be wider than the factory fit 14", 5.5 wide ones ... but that fast manual steering on the "S", and a chance at another 64 Belvedere made me forget about being a rally driver in short order!

So possibly the 468 wheels were small pattern, but I never ordered them, so this is quite literally 56 year old memory speaking so take it for what it is worth!
