so here is my end result
tightned by hand with 9/16 socket untill it stopped and locked the jam nut took it for a ride and its never sounded smoother.
a few extra things i encountered
1. there are pieces of the chaincase cover that are mad in that location to hold the auto tensioner in its place so that the chain stayes tight ( l m f a off what a joke)
so i had to cut these slivers of aluminum away so that the cover would close. drilling the hole was tricky getting it strait without moving the bellypan.
2. other than that the project went pretty smooth and works like a charm i got my product from One Stop Performance (OSP)
$155 shipped
it was either that or wait for one in feb and not ride my sled till cat decides to make more... wasnt waiting bit the bullet and now im golden
