I'm looking for a replacement Guido - driveshaft Flex Disc. The Toyota/Lexus part number is 3751124010. It appears to retail anywhere from $175-300, what!? I can buy a BMW, Mercedes and many other makes Guido new for like $30. Why are they so expensive for the SC? Does anyone know where I can buy one for cheaper? Or, does anyone know if there is one from another car (different make and/or model) that is the same as, or close to the same as the SC's and compatible. These are a pretty generic part and I would assume if the bolts line up and the thickness is the same they would be interchangeable. Mine is shredding to pieces and I cant drive the car anymore without fear of having it blow apart completely. There are two on the car and I'm not about to spend upwards of $300+ on two small pieces of rubber. Any input is appreciated. Thanks!
