Wondering how much of 02 regal will match up to the 03 Lasabre. Same 3.8? Suspension? Electrical? Thanks in advance for your experience!

I work at O'Reillys so I've got a good interchange source there, just wondering because a family member just got a lasabre and needs some work...

Engine ( if same engine) and electrical parts are mostly the same, Body and suspension some parts may be similar. But as said enter what parts you want to interchange into a GM or parts site and compare the results
