But that is DOHC. However it is a one year only swing arm. You could swap it with an older uglier square, ribbed one off a 77-78, or an even uglier, and shorter one off a 69-76. These will all be bolt on. Now if you want to go to some work, you can swap on an 80-83 swing arm that will look just like the 79 swing arm. You would need to cut 1/4 inch off each side of the swing arm, and the bushing inside. Then drill out the mounting holes to 5/8 inch. Also you would need to cut down the bolt, or make spacers.

I have seen some pictures of guys replacing the stock or similar version with a boxed swing arm, I see some guys like Carpy make a swing arm like this ..

now you had mentioned that some of the SOHC earlier model swing arms do fit so I assuming this would bolt on as well??

he gives the length but not the width

now i am not sure if those are available currently however, i see some guys upgrading to boxed swing arms.  I have two '79 ones because I did some damage to the pivot collar when I was a noob removing it because of the nylon bushings that were rock solid.  That is what I am using now.
