Many of the numbers are the end of a part number like if you have 891 + 892 in the torsion bar section you can go to the proper year parts book and look up torsion bars and look for your car type and the last 3 of the part number. Then the description tells you what it's called.
Not too many options......it's a 1971 Slant 6 Duster, 225 engine, 904 transmission, 2.76 rear, A/C, tinted glass, 50 amp alternator, AM radio, power steering, woodgrain steering wheel, bench seat. That's about all I can read.
