If you don't care for big wheels...

As one who typically despises wheels larger than 15" diametre , I must admit that these look very nice on your '72 :glasses7:.
For the same reasons mentioned previously , it's the fact that they're not some gaudy ghetto-cookie chromed-out monsters with some hideous design ; and 18" diametre isn't too bad .

I'm concerned by the lugcentric retention as opposed to hubcentric , as now those spindly '72 & earlier studs are carrying the load ; definitely no bueno !

As a side note : I've always preferred the '72 grille to the '70 / '71 grille , as it just looks cleaner , parking lamps and all ; those horizontal lines really clean it up nicely .
