NEED rear disc Conversion for 510

[NOTES...]

I have a 71 Datsun 510 and would like to know if anyone in the San Diego, Inland Empire area have a rear disc conversion... I would like with the brackets and every thing... I Have the rear disc and caliper from a 81 280zx but don't see any brackets for those so I'm down to buy someones that's already ready to install... I believe the easiest is the 82-83 200sx... But i don't have time to go to the junkyard and try to find them.... pm me please
