Hello PJ, I need to know what the air-gap should be set to on the Ogura brake/clutch. I need to nurse it until I can get the Warner mounting kit. I have a Warner Mastop model 5218-65 and need to get the part# for the mounting kit. Also please check to see if this is the correct Warner clutch part#. I wasn't having much luck finding out on my own. Thanks in advance. sincerely, Kenneth Leak.
