I don't know if this will help or not but here is an example. My 180 has a Cleveland kit available, number 199-62. I can put that kit on my airplane using a Cleveland stc (I can't remember if it actually needs an STC but the gist is the same, it's approved on my airplane). The main wheel of that kit is Cleveland part number 40-75d. ABI makes a PMA equivalent under ABI part number 40-75d. I can replace the Cleveland wheel with the ABI PMA part with a logbook entry. Now if you wanted to replace the Cleveland wheel with another part number that was not PMA'd for that Cleveland part number, you would have to get a field approval or an STC.
