i have the trunion rebuild by harland sharp. i forget how much it was but i sent them my brand new rockers at the time.
i think it was 200-something. Def worth the upgrade. i got tired of all the high rpm loss of the needle bearings.
Since i bought a brand new LS6 crate engine, i just unbolted the rockers and sent them off. I made sure they convert my exact mint brand new rockers not just give exchange me a set. All went perfect.
