clutch for 4.3 silverado

i was wondering if anyone new of any aftermarket clutches for a 2005, silverado with a 4.3l 5 speed, and if the drivetrain is the same as on a v8 model the truck is a regular cab, ive seen clutches for the v8s only unless they are the same with the v6, any help would be appreciated thank you.
