Has anyone on here successfully used the 1999-2002 2wd s10 blazer rear disc brakes on their G body? I got the set up cheap from the local LKQ but I'm sure if they will work.. Just curious if anyone on here has done this swap?

Jake has done the blazer swap. Having a brain fart on his handle name on here. I just begun teardown on mine to do the LS1 F body rear swap. They're essentially the same thing. Next step is to drill out the 4 mounting holes, and trim the top of the flange from the Axle ends...

GM kindly reused the lower two bolt locations in their traditional trapezoidal pattern for the funky Gbody backing plate retention screws. I used these as alignment guides and pilot holes. Locked one down with a bolt and then marked the upper two locations. I think the Blazer plates use exactly the same pattern as the LS.

Yeah, 2wd blazer absolutely works.

I did it wrong and used 4wd backing plates due to 2wd stuff being unobtainable up north, but the only difference is I switched sides of the backing plates so I put the calipers on the back side and fabricated a new Ebrake cable bracket. Calipers are the same.

But that's what the flange looks like post-cut. It's the same for 2wd or 4wd backing plates.

Thanks.

I haven't used them much, they are a bit of a pain to actually use. I intended for them to lift the back of the car when I drive between track to track on drag and drive events when the trunk has 700lb of tires and tools. However, unless I drop the rear end fully & remove the shocks and twist them up, there's too much weight on them.

If I were to do it again I would go through the trunk or just put an airbag in.
