J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Boom Vang Repair

Hi Guys,
I recieved my Sleeve from RigRite today.
The sleeve is a half inch too small. I expected a close fitting sleeve. Has anyone else used this K-11903E sleeve?
I want to reinforce my boom at the vang. I don't see how this would help being so loose fitting. I could just use an aluminum tube stock instead of this for my $200.00. Let me know if I need to send it back to RigRite. They assured me it was for the old style boom, which I have. See photo.
Thanks
