10 "x 1 3/4 pad x4x5 bolt p. drum available?

Looking for a 10 drum to fit my new 1 3/4 " pads. I bought pre loaded brakes a long while back not knowing these drums were hard to find. Guess I could look for a 10 x 2 1/2 set up or go complete disks but read that the disks would require me to go to a larger rim. I'm running 14 inch rallies. I'd rather not change complete direction at this point. Any suggestions?I have 4.5 bolt pattern.
