T Bar in Distributor

I didnt mark the T Bar I pulled it out of the STOCK distributor.:banghead: I'm welding the slots as suggested to limit the mechanical advance. I'm not running vacuum. I thought the T Bar was the same but, I didn't account for the rotor. How do I get the proper orientation of the rotor slot to the rest of the distributor. How do I keep it from being 180 out. Make sense what I'm asking?
