difference between bushing sizes for total chaos and camburg UCAs?

Hi recently i was hearing a funny clunk on the passenger wheel well, i check it out and im missing bushings from my UCA and want to order some new ones,
however i bought my truck used and have no idea on what type of UCA's it has so im not sure what to order, i believe they are total chaos or camburg but im not positive any help would be appreciated

 

Any ideas?

 

I don't think they are Camburg.. They use a 1.25 bearing and a different top spacer.
If you are missing a bushing, get a measurement of the ID of the arm and let me know.
