Ii bought a 49 Buick that has a 455/TH400 from a 1974 LeSabre. I know that part for sure. It also has a 10 bolt GM axle with 4 link suspension and drum brakes. It's a 3.08 as best I can tell. Did this also likely come from the same donor car? Thanks! I am trying to figure out how to buy parts for this car.
