Yeah, should swap fairly easily. You will have to replace a few other parts though to make them function properly. If you want rear disc's, just buy a conversion kit and use your old R/E. The R/E in the blazer may not have the same gears as yours. Could affect gas mileage / power ect. On a good note, the effect could be good.
Swapping is ok but better be careful when you do it coz they might give you brakes that dosent function well...Just found out that the coil springs were broken when I swap the suspension of my car to a much newer one...
