The buds on my unit don't have any letters (L or R) so I'm thinking it's anything goes when removing.
Take a close look at the threads and you should be able to tell whether they are RH or LH.
AT FIRST you can probably ASSUME that studs/buds/nuts on the RH side are RH, & studs/buds/nuts on the LH side are LH.
Try to remove them w the air gun using this assumption & IF THEY RESIST take a closer look at the threads.
IF you are removing using hand tools it is probably a good idea to examine the threads 1st to determine RH or LH.
Might save you a few scraped knuckles!
AND might keep you from using "colorful" language!!
Remember that for NORMAL threads:
"Lefty Loosey, Righty Tighty"
(MY MIND struggles to accept the opposite when threads are reversed!!)
