yea, I found that too last night and yes, my vin is 4722920XXX
I'm a little frustrated at that, since these are VERY new (< 200 miles on them) and I didn't want to buy a new set (AGAIN!)
I had remembered someone telling me that they changed some things in the front in mid-'72... but didn't know what...
c'est la vie... well, SOMEONE is getting new rotors and wheel bearings with the roller!
at least I don't have to buy a new master cylinder too
