Gotcha. Yeah RWD configs won't work generally speaking. Lots of hassle there. Definitely wouldn't be worth the donor car effort as you wouldn't be able to use half of what you're looking for.
You could try putting a feeler out there for an 08-12 altima coupe 3.5 donor or an 07-09 Altima sedan 3.5 donor car in the following section:

Otherwise, as far as insurance company sales sites are concerned, I'll leave this thread here as it is a more general question and you'll need the gen chat traffic for that.
