Is 68 GS/Skylark Top Frame Same As 69 or?

70 71 or 72?

My top frame is bent to the point it will never look straight.
It does work but it looks like hell and the frame hits the LR quarter window.

Some members have frames from years other than 1968.
Can anyone tell me if I can use another years frame on my car?

Thanks in advance.

 

I'd guess 69 for sure, don't know about other years.
