1974 r75/6 stock bike looking to add sidecar. Simple lightweight for a dog mostly. No brakes for sidecar. Just a very basic light rig. Almost what you would see on a klr. Looking for any ideas / suggestions. What frame / mounting hardware would be best /simple. More I think about this I am looking for a platform to put a medium dog crate. Lurking here and love the builds I see on the hacks.
