Will a 1978 F swingarm fit a 1978 K with no mods?   

Thanks.

I can tell you that a 77F swing arm will fit a 77K.

You will need the shorter swing arm bolt from a K tho.

yes it will fit the frame with no mods. you will need the shorter k pivot bolt.

if you are using the k's drum brake though, you will need to weld a tab on the bottom of the f's swingarm for the brake stabilizer bar to bolt to. the f's swingarm has the tab on the top of the swingarm. to be used with the disc brake.

also may need some different axle spacers if you fun the k drum. the f hub is different from the k, and the f's caliper mount acts as a spacer also. i dont know for sure, but you may need to cut spacers to line up you sprockets.
