Hi, can i use this guide to make the snsc dual drive?

It's pretty much impossible. You would need weld and use an angle grinder. also you would need to use some kind of 3rd party hinge with a locking mechanism. It's not worth the time

If this guide didn't help you enough or if you want clearer pictures check out this page:

Enligt expressen ska linköping snart få Voi, om de inte redan har fått dem.
