AMEN!!!!!!!!!

I have an extra small spline T case input hub. Came out of my 03 1/2 ton. I swaped it out for the 31 spline hub. If you need one let me know.

Thanks!! I still have the old T case with smaller spline. With stock trans in for now I think I'll send trans back to FLT to get larger shaft. It should hold up until I get it back. I might just run less boost for now. Orrrr just see how much the stock will hold

i understand the 2wd and the 4wd tail housings and shafts are different. thats a no brainer. what i didn't relize when i wrote that is that the trans was made custom for a awd t-case which is why it had the smaller spline output. i found that latter last night which is why i said *edit* found the thread, now i understand."
