This a very broad question. Do all wings work with all plates etc?
For doubles the answer is yes as far as I know. The one thing that is standard on plates is the 11" spacing for the tank band bolt holes. All plates have atleast one set of holes, some have more than one set for trim adjustments.
If using a Single tank adapter with most single tank wings and plates angain the answer is yes, almost all wings will be compatible with almost all plates, because again the STA uses the holes at !!' centers.
Where there is potentially a problem is when a single wing and plate is to be used without a STA. In this case the camstraps must pass thru slots in both the wing and the plate. These is no standard for the location of these slots in either the wing or the plates. In most cases there is not a problem, but the potential exists.
I am always very reluctant to state anything about other manufacturere's plates. I have no way of being sure that their design has not changed. Remember that untill quite recently many plates did not even have slots for single tank mounting at all. I might have one example of Brand XX plate that works OK, but it might be last years model, version 1.0 etc.
Our single wings have holes at 11 centers, so they can be used with an STA if so desired, and the cam strap slots are 3 inches long, so some range of misalignment is accomodated.
