Mr70:I read somewhere by one of the Z-16 authority's,that although similar,the Z-16 did NOT use the 1965 Chevelle Convertibles' exact boxed frame.It did resemble it though.Also the Brakes were NOT Impala 11" brakes,but similar as well.
Both were unique to the Z-16 Chevelle.

OK,Jeff was kind enough to clear this up.Thank you Jeff.

By jeffschevelle:
The Z-16 frame has a different part number due to a different front cross member (there could be other differences but that is the only one I am sure about) They started using the Z-16 cross member in all the frames later in the year,but did not change the part numbers as a result.
So the Z-16 frame part number remains a Z-16 only item.

The rear brakes are entirely interchangeable with a 65 Impala.The rear axle housing has Impala size tubes and bearing housings and flanges on the end. The axles are Z-16 only (Chevelle length with Impala diameter).

On the front brakes everything inside the drum is interchangeable, but the spindle, backing plate and drum are Z-16 only. You can use an Impala drum with Impala wheels, but a Z-16 wheel will not fit on an Impala front drum. The front brake hoses are 1st gen Nova.
