Which one do you need, short or long? Most PLM headers utilize the short version. Once the slip-fit collector is fully inserted, the short version hardware fits perfectly. On rare use cases, such as the H-Series Ramhorn header, where the 4-1 merge collector needs more adjustability, you will need the long version to allow more play in the slip-fit collector.
