1. Are ARP steering knuckle studs worth the $$$ compared to the new "stock" ones Marlin sells??

2. Will U bolts for a mini work on a 40?? Same Size (Marlin sells these)??

3. Does a stock birf have any identifying markings on it?

4. What year axle came with a stock 30spline birf??

Thanks! Dan

2. I don't think so. I think the axle tubes on a LC axle are larger in dia. than the tubes of a mini axle.

I agree, but wasn't sure.

Confirmed...mini u-bolts don't work with 40 housings.
