05 Colorado disk brake up-grade
 

A friend and I were discussing the possibility of getting rid of the poor rear drum braking system on my Colorado and installing Hummer H3 rear disc braking system. The H3 is known to have the same frame and rear end as the Colorado. Planned on calling our local junk yard to see if they had a wrecked one there and see if the system would convert over. Does anybody have knowledge of this idea working??
