curious if the disc setup on a nine bolt will fit a gm 10 bolt. i have a 9 bolt with 2:77 and i want to go to 4:10 so i am going to use my ten bolt but was wondering if the disc brake setup will fit on my ten bolt so i can replace the drums

 

With that combo, you'd be better off staying with the 9 bolt and upgrade the gears.

9bolt.com will have spacers to use lower gears on the 2:77 carrier. Cheaper then getting a series 3 carrier and gears.

 

the 10 bolt rears and the 9bolt rears have differant flange pattern for the backing plates. (to answer your question!)
