Yeah, it was seized in the hub something awful. I used shitloads of pb blaster, followed by torching the hub. I ended up mushrooming the top, i ground it down, used a thread file and its still fuckered up.
I found some dies in that size online, cheapest i found was 40 bucks which i may end up doing because the halfshaft lists at 395.06.
thanks for the input fellas.
