Put in the Barnett Carbons and springs also. Fixed the slipping but, does make a harder shift and neutral find. Some folks use the dimpled stock plates. Says it traps oil and reduces heat. Something to consider. Didn't shim the springs (didn't come with any) but, doesn't need any more tension anyway. Hooks up just fine under heavy load. Did use a touch of Blue Loctite on the bolts, just to be sure they don't back out.
