Welcome to the forum,
IMO
Old Hot Rod skills won't help much when it comes to EV's.
Maybe a little bit when fabbing & mounting the components
...but, not much for the actual "EV stuff"
I'd start off by doing lots & lots of research (it's free)
Watch how others have done their conversions
...take note of what seems to work
...& also, what looks kinda "janky"
Try-n-copy what works (in your own way of course)
...& don't do what didn't
&
If you have any questions
...ask away
