Yeah If I could get a conversation kit for my 01 Tacoma I'd be right fucken happy, I'd even sacrifice a quarter of the bed for battery space if need be. Would still have 2x the bed space of a cyberclunk as well.

There's a small company party near to where I live that converts ICEs to EVs.

Bottom line is that it's expensive as fuck to do so and the clients are either well-off folks that want an electric version of their favourite historic car (DeLorean or 2cv or something like that) or companies that calculate much differently, with six digits worth of km on their delivery vehicles. It's not economical to do that to an ordinary car with ordinary kilometres per year.
