How do I know which pins and bushings fit my Cat EL200B or 320 excavator?

Fitment varies by model and series, so the most reliable method is to match the part number stamped on or listed for your original part. For example, some links and seals fit only the 320, 320L, 320B and 320BL, while others also cover the 320C and 320CL.
