olds 88

Hey I have a 96 Oldsmobile Delta 88 I was wondering if I could switch my analog dashboard with a digital dashboard from say a 93 eighty eight The harness plugs look to be the same and I was wondering would this work and would it just be plug and play?? Help someone

I drove my car for about 2,000 miles within 4 days with no problems...One week after that, I just drove like 100 miles and when I put the shifter in the "P", there's a loud rattling noise coming from under the hood..It just started suddenly, no warning..It's really loud (embarrassing!) in idle...
