"FRONT Brake"
22 = Should have a blank spot in H/DUTY OR DISC? = 10x2-1/2" drum assemblies
23 = Should have B11 in H/DUTY OR DISC? = 11x3.0" drum assemblies
29 = Should have B41 in H/DUTY OR DISC? = disc brake assemblies
59 = Should have B42 in H/DUTY OR DISC? = TRANS AM disc brake assemblies

figuring what was included in each assembly: everything between both control arms - more or less? might be more difficult

what is the difference in original components of "disc brake" VS. "TRANS AM disc brake"?

left VS. right might have been as simple as the assemblies being marked xxxxx22L & xxxxx22R on the assembly line? shruggy
