Dw616 vs dw618

Hey guys,
I’m new here and in the process of building my lowrider2.
I have a few questions I hope someone can answer,
First,
I have a dw616 and was wondering if it uses the same mounting pattern as the dw618 because I can find files for the 618 and not the 616.
If not then I can measure my hole pattern and make it to fit.

Second,
I have aluminium for the plates but I am having trouble finding a template to cut them out. I was hoping someone could direct me to a 3d printable STL that I could use to print and then trace.

Ps I have an ender 3 so the STL would preferably be already cut in two to fit on my build plate. But a full STL would work fine too. I thought I’d ask if someone has done this before I spend time on my super slow PC to make it myself.

Thanks in advance! I look forward to sharing my build.

You can find the DXF files for the plates along with the STLs on thingiverse. I believe people will print those out on paper and use them to cut their stock if they are not buying them directly from Ryan’s store.
