I have a 1972 chevellethat has been wrecked and has a bent frame. I have a chance to buy a good frame from a 1972 cutlass to replace it and have been assured that they shared the same frames. is this true? or would it be a waste of money?.

they are exactly the same as long as it is a 2 door hardtop. meaning not a 4 door or a convertible. ;)
