manual front drum to KH disc swap

Ok ... class... sorry you guys needed my life story ...
1. i purchased USED kelsey hayes parts from DART540...
2. 1 hub JUNK ...
3. Looking for another HUB .. cannot locate 1 lonely hub ..
4. Upon replacement of the new hubless rotors from DART540 that came in the package ... i noticed that the rotor center would contact inside of caliper ... Well i am not goint to GRIND the caliper like some of you might ...
5. SO i decided to order 1 new hubless rotor from the RAMMAN ... surprise NO rubbing ..
6. If i had to do it again next time and in need of 2 rotors .. i may consider the RAMMANS rotors and may also consider upgrading to LBP..
How is that for an explanation ????? DO YOU understand the words that are coming out of my mouth
