That's easy, Fluidyne used to do a lot of manufacturing outside of the country and Fluidyne was run by someone other than Gary (old employee NEW current owner) when the problem occurred with the incorrect mounting points on the batch that was produced a couple years ago that got shipped all across the world they were shipping a lot out without it even landing in the house of Fluidyne allowing for errors and lack of quality control. This is something he regrets to ever hear about. Then Gary stepped in and took over the business and changed all that to developing and manufacturing 100% in house (Moorseville, NC)and I will post pics to prove this and has been doing so for over a year now. In fixing the problem with the Supra cores he took the similar dimensional design and are using the 3 row feature and have done away with the single core they had before. I had a long conversation on how to reintroduce the Fluidyne product back into the supra industry and he assures me that as long as he has a reputable company to handle the product then there will be no issues. If problems were to occur, Gary would send a call tag for the core and have it replaced or refunded. The first batch will come here and personally be test fitted by me and will take pics of the perfect fit. Also they were just picked up by JEGS as their newest large domestic distributor.
