Sidecar rigs ARE A BLAST! (Once you hack, you never go back!)
In the mid-80's, I built a conversion rig out of a early '60's /2 that already had a car on it, but with a blown engine.
I put a R100S engine in . It worked out well.
I have never seen that particular model car before. You might want to think twice (and show it around some sidecar forums) before you take the knife to it.
If all you want to do is use it for cargo, consider removing the body from the frame, and building up your own.
And I am a sidecar-building snob. I would never consider using any /5 or later frame for sidecar use. The Earles-framed bikes are so perfect for the job.
It is easy to "fly" the sidecar in a curve in which the sidecar is attached (left side in the British "empire"), but I really impressed myself when I found I could pull up the sidecar in a R-H curve (USA), and keep it up and go through the following L-H curve in a 'S' curve!
Once it is up on two wheel, the bike behaves as a normal two-wheeler (counter-steering), albeit with some weight hanging off the side! Very controllable.
AND A FRIGGING BLAST IN THE SNOW!
