the front frame horns are different
Yes they are. Almost all of the sport frames have interchangeable lenses.
Absolutely NOT!! They are two entirely different frames and two entirely different cars. The Impala is a full size car while the Chevelle is a mid size car. You CAN use a frame from the other GM A bodies from '66 and '67 with the same body style (coupe, sedan, convertible, etc.) so a frame from a Buick Skylark, Oldsmobile Cutlass or Pontiac Tempest/Lemans will work with VERY little modification, if any. The only thing you would need to change is the motor mounts. Everything else is completely interchangeable.
Yes
Alot of normal inline skates aren't interchangeable, but some are. Usually you can't put aggressive frames on, but if your using K2's, you can/
No it's too short. Correction, 1961 to 1964 Chevrolet passenger car, 2 door or 4 door frames are interchangeable. Station wagon and convertible have differences.
A 1974 Chevy Impala frame would work
A Trans Am is a uni-body frame and the Malibu is a full frame. So absolutely not.
Considering the fact that the Trans Am is a unibody and the Malibu is a full frame car...NO
A frame from ANY '68-72 GM A body convertible will fit because they all use the same frame. I'd stick to the convertible frames because they are reinforced to deal with the lack of a permanent roof.
YES,All 1968-1972 gm a-body ( cutlass,chevelle,skylark,gto) can be interchanged.
ANY '64-'67 GM A body frame from the same body type (2 door coupe, convertible, etc.) Now, you are MUCH better off sticking with the '66-'67 frames. Even though the earlier frames can be used, the '66-'67 frames are stronger.
In those years they were not interchangeable.
