The link I posted goes into every single piece of the transmission in detail and exsplains what materials are best for your exact engine ,not just some kit.You can get every single piece individualy,based on your combo .The site goes into more exsplainations of parts what hp and torque they fail at and why,than any manual you could purchase.
Buy what you want from wherever you want.........but this site will educate you on exactly whats available and why.
