Frame Interchange - 67 B Body

I have a front sub frame and rear frame rails from a 67 B Body. Pretty sure they will fit a 66, but will they fit anything past a 67?

Front would probably work up to 70 , though there might be some subtle appearance differences.

Rear , I don't know if the rear overhang is the same length past 67

Front clip is 66-70. Rear frame are 66-7. 68-70 are pretty much the same except 66-7 has previsions for the fuel tank mount as where 68-70 are different.

Mark knows all sorts of cool stuff.

Thank you very much!
