DOES THE 1973 DODGE CORONET & 1972 DOOGE CORONET GRILL & HEADLIGHT BEZEL INTERCHANGABLE ?

I would doubt it. The front was changed for 73 because the front bumper became impact absorbing. The sure way to find out is to check a Hollaner's Manual. It lists interchangeability.

we'd know if you could put a picture of each...but you dunno...neither do we~

After checking Google images, it appears that both years used the loop bumper, so there is a very good chance the 73 grill will fit the 72. The grill texture will be different, but the shape should be the same.

Yes it will fit it's just bent a little different same bumper
