WTB good used complete dragster diff / brakes / etc

Have a Top Dragster that we will back half this winter, and want to replace the old fabricated rear end housing & spindle / brake assembly with something pretty current,, like a Strange or MW set-up. CF brakes not req'd.
Car runs 6.20's, so it's gotta be strong.
Please let me know what you have.
Thanks!
