First splitboard setup questions

Hey everyone,

I just bought my first splitboard setup: a Jones Solution with used Spark bindings. I'm stoked to finally get into touring this season.

I need to adjust the puck position because they're not centered for my stance, but since I bought everything used, I didn't get the alignment tool.

Is there a reliable way to align the pucks without the tool, or is the alignment tool pretty much mandatory if I want them set up correctly? Any tips or tricks for getting them dialed in?

Any other advice you can give me about my first splitboard setup would be greatly appreciated.

Thanks!!
