OK but your not going to like it... I contacted a company in Ohio called Hercules manufacturing... turns out that they are the only ones who import for MWM Brazil in the entire U.S. Don't expect anything but heartache while contacting these folks. The owner was who I had contact with the whole time and the guy acts like you are an inconvenience and not a customer I was directed to the owner from the other employees at Hercules BTW. I did get my parts, but only after I sent an email to MWM Brazil after months of basically getting the run around from owner of Hercules and they got all over his ass about it. If I could have gotten the parts directly from MWM I would have. I would text the guy directly and 3 weeks later text him again just to keep on him, and 99% of the time he wouldn't even be courteous enough to give a quick reply back on the status of the order. I hate to recommend these guys but unless someone can cross reference the numbers to a generic starter from autozone or something your screwed. I will open the crate and pull out the starter and get the starter part # for you here in a little bit... hour away. Even though Navistar owns MWM I went to a Navistar (International) dealer in Vegas and the guy working there claimed to have worked there for 26 years and knew nothing of MWM or that Navistar owned them, he even aked the main guy there and he knew nothing of the merger or of MWM, that and they acted like pompous asses anyway.
SO... The growler and its parts system sucks! I played stupid and texted the owner back a couple of weeks ago and said I had a friend who needed a flexplate... he claimed he checked with MWM and the don't make a flywheel... I asked about a flexplate and he tells me they don't make a flywheel... I ALREADY HAVE A FLYWHEEL, I need a flexplate so I doubt the guy ever checked with MWM he just said that so I wouldn't both him anymore.
