This is the plate that goes under the rear axle (GM 14 bolt) and accepts the U-bolts. We have them as take-off or as sandblasted with paint (shown sandblasted w/ paint). May fit other axles, but designed for a 3-3/8" tube and 2-1/2" wide springs.
These are the solution to your rusted out plates! Sold in PAIRS (you get both sides)
