So it is true about pistons being different sizes for some calipers that otherwise look the same and bolt up the same. I wonder if there is a part number reference for this?
Sedan/coupe rear caipers-123-420-05-83
w126 300SD------123-420-05-83
w126 420 sel------123-420-05-83
wagon rear calipers-123-420-12-83
t walgamuth is correct...A quick look at the part numbers on here reveals that there is a difference in the part numbers. It appears the wagon rear calipers are different.....is this the number that is stamped on the caliper itself or is there another number to differentiate?
