8.8 swap
I'm also installing an 8.8 in my 68 Dart. The price was $200 plus $37.50 for a short axle.
It looks really good inside, the bearings and gears check out good. I'm just going to replace the axle seals and run it. On this type of c_clip axle replacing a axle bearing requires a new axle because it is the inner bearing race.
