The 8 1/4 thread

yup

sometimes its hard to change directions and buy a whole new setup when you have already invested so much into one that wont work. I was lucky that I had the right setup and after a ton of research and twice as much doubt i only had to change a couple bearings.
Your right about changing directions I've machined the carrier to move the bearing in more.The housing was plenty thick. A shim on the other bearing and I'm good to go. now does anyone know the right pinion height from say the top of pinion to a dummie bar bolted in the carrier bearings? Thanks for the input Jim
