update
I was thinking I needed some way to stop the motors and mounts getting a beating, I initially thought I’ll get @akhlut to help me make something alu I can use ‘just like the front part of that indy base plate’ occurred to just dremel one in half
ending up with something pretty much exactly as I imagined 
not really necessary at all but I like it
little tidying todo but I think this might just work
EDIT: almost forgot the best bit I’m going to reuse the kingpin hole to hold the charge port
