The Stovebolt Site Forums The Shop Area Driveline Where to get 3.55 ring and pinion for 48 gmc

My stock differential was in good condition, no issues. Did the 3:55 gear swap.
I did not buy the install kit.
Used the template on the DEVE site to make the spacer tool.
Purchased OEM shims to set the pinion depth. The bearing can all be reused and no pressing or cutting is required to swap the gears.
