Hobie 20 Travler Maintenance. Harken Data Mismatch my case.

Upon removing my traveler, I found that this information was incorrect for my case. 

Installed Torlon/Delrin Balls are 8mm for me, not 6mm

End Caps cracked on both sides, but still retail balls. 

Replacement parts $22 for both sides - quite a profit margin for Harken:
