What's the Difference Between Similar Part Numbers?

Part numbers that look similar often have important differences that affect fit and function.

Common Differences Include:

Length:

• Example: RR 110-I (6 feet) vs. RR 110-J (8 feet)
• Always check the length specification for your application

Steel Core:

• Parts ending in "-M" often indicate a steel core (molded)
• Example: VS 3 (extrusion only) vs. VS 3-M (with steel core, molded to fit)
• Steel core provides better rigidity and hold

Molded Ends:

• Some seals have molded/finished ends, others are straight-cut
• Molded ends are designed for specific applications

Body Style Variations:

• Some part numbers are for hardtops, others for sedans or convertibles
• Read descriptions carefully
