California Throttle bodies

Hi, has anyone rebuilt California throttle bodies?
I have some serious sideways movement on my L/H throttle body. I noticed this whilst reading the TPS setting and tuning and balancing the bodies. I have been on “WildGuzzi” and downloaded the info on there about V11 bodies and would like to know if there is any major difference between the parts required to re-bush and replace the seals between the V11 and Cali bodies.
Thank you in advance for any replies.
