I have a 1995 SLE (as stated in Sig) I am thinking about in the distant future swapping in a 3800 Series II */C ....what would I need to do this exactly, how much work would it be, etc etc....?

Factory Service manuals for both years of car (yours and the donor)

I suggest selling your car and buying an SSEi for less money. And you'll get the rest of the options and features you don't already have. Sunroof, HUD, FE2 suspension, etc.

Thank you for the list. I also appreciate and realize your suggestion, i'm a person that has in the past had to do things the hard way though so be warned lol... My car is more than just a Bonneville to me, more than just a car, it'* the first car i've had in 3 years since my last and it'* been great to me. I've spent plenty of money to undercoat it and change the suspension over to FE2 now and whatever else. Basically the point I am trying to make is there is no selling my car lol...I don't play on buying an SSEI, although I do plan on dropping a Series II */C into this no matter what it takes. So with that in mind, along with the list you gave me, how much work really is involved, like what is going to have to come apart, etc.?

I sent you a pm about your idea
