I bought Cronetec's solution from their website and installed on my 2001 Blaster. I'm quite pleased with it. No need to swap out your carrier for an 03-06. No welding or custom fab. I filmed my effort along with the parts I used for Youtube here if anyone is interested or just search 'Yamaha Blaster Cronetec'.
