Looking for some help finding a replacement mainshaft for my manual transmission, I believe the trans code is M50D-R1HD. It's an '07 4.0L 4x4. I ordered a shaft from Transparts Warehouse, thinking it was the right one, but it's not quite the same. I feel like I've searched high and low and none that I'm finding look like what I pulled out of the trans, any help would be appreciated!


old shaft vs M5R1-2 from Transparts Warehouse

See my introduction thread for a little background of the truck.
