Just how much cutting?

I didn't fix the rust in the floor of the trunk; since I planed to cut it out to put in the conversion parts.
But now; I'm thinking maybe I don't have to cut as much as I was thinking:

The front looks great for space, and really I just need to bolt the rack it.

 I got all kinds of inches to spare.

 

The read trunk though, while I think things will fit.  Looks a bit cramped

 

 There are no bolts in these batteries, so you have to imagine a half inch more.

So I think I'll cut into the trunk anyways.
