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
