Is It Possible To Put An After Market Cd Player In My 95 Lesabre Without Any Massive Modifications.
Any Suggestion On Models?

Yes, very easy. All you need is a kit that makes the aftermarket CD Player fit in the dash opening, an adapter for the power/speakers and one for the antenna.

Wal-mart has these kits as well as Crutchfield. If you want to familiarize yourself with what you need, you can go to the Crutchfield website and look at what you need (make, model, year). It will show you a list.

P.S. I've put 4 in my 97 Lesabre. I have it down to 20 minutes complete for a stock replacement. It's not hard at all.

You may also need to get the serial adapter to make the steering wheel controls operate the new radio.
