928 Motorsports: Purchased their 6 speed conversion kit. As others have found metal shavings in the driveshaft. Unfortunately 4 other customers found and posted the same problems. 2 of them had failed driveshaft bearings less than 2000 miles after the kit was installed by the vendor. I let my kit set for years before discovering the metal shavings in the sealed driveshaft which is part of the kit and was shipped to me sealed. The bearings that were installed were rated at 5K RPM & one of them had a dent in the seal, appearing as if someone installed it with a punch or a drift tool. I also had issues with the transmission brackets and the vendor attacked me on this forum as he has other customers. Vendor refuses to take customer feedback to improve his products, and most if not all of his products are half baked and are not bolt in replacements. I will post separately.
