Dana 300 clocking question

I'm wondering if there is a reason that you cant drill the holes for a flatter clocking position into the stock adapter between the trans and T-case. If I remember correctly the T case side is circular with holes in it.
Seems like every one buys an adapter or taps the case.

I don't have mine handy to look. but is there a reason why this isn't done?
I'm thinking you could just weld up the old holes if needed and drill new ones in the desired location.

Clocking rings are so cheap that I would not even waste the time on what you are planning. Also using a ring will give you more clocking options.

There's no need to weld up the old holes. If you're only clocking it enough that the old holes would be in part of the new hole, you might as well just leave it alone.

If there's enough meat on the adapter to drill it, by all means, drill away. Not all adapters have enough meat though all the way around, or there may be other obstructions like support ribs where you want a hole.

Be advised, you may have to cut off the inner ear of the shifter bracket to clear the side of the transmission.

Considering you have to compromise the strength of the bracket, modify the trans cover and/or tub, fab a new skid and trans mounting bracket, and modify the shifter or go twin sticks, I decided clocking the T-case wasn't worth the effort.

Your mileage may vary,

Matt

I redrilled my Novak adapter. As CSP said mine had ribs on it that I had to miss. I clocked mine 6* as there was a rib in the way at 7*. It hangs about .75" below the frame rails now.
Do be aware that the holes are not on a bolt circle pattern (not evenly spaced)

I redrilled the holes in the adapter face. No issues.

Beat it to fit, paint it to match!
