No.
YES.
Yes no difference. Wrong, A 66 Chevelle and a 65 are totally different hood styles. 66 and 67 are the same
Yes. It will bolt right on.
No. It will fit the 1966 and 1967 Chevelle only. A 1967 Skylark hood will fit if you can find one.
no
if the buick is also an A body they will work as the chevelle is an A body.
Try looking under the hood for the vacuum hose decal or try a junk yard the decal might be under another hood.
It will bolt right on. You WILL need a headlight wiring harness from a 1970 as well since the '70 has 4 headlights instead of two like the 1972 does. A friend of mine did it. You cange the whole front (fenders hood grille etc.) and throw a 1970 rear bumper on and your 72 is now a 70. Your friend changed more parts than he needed to. The fenders and hood are identical from 1970-1972. The only body parts that are different are the headlight buckets, grille, and bumpers. Now you certainly can change everything, but it's not necessary.
No. 2 different body styles.
Right above the front license plate.
There is a decal under the hood with the specifications on it.
