Here's a 49.
For me, I'd keep looking. I prefer the 40-48 body, except the 41 front. A 4 door will never return the time and money put in. A 49 is (to me) a more frumpy car. The only ones of that era I'd consider are a 49 business coupe (think High And Mighty) or the fastback 2 doors. This is just me though!

Drivelines and suspension are very similar, 41 has a huge crossmember, preimeter on the 49. The 49 will be easier for the exhaust routing. Since both need floor work, that's a draw. Are there parts missing that you will have to track down? That can be tough. The car istelf is usually not the biggest expense on old mopars, so get the best one you can afford.
