Best strut mounting plate

[oleSilverado]

Having a rattle in the front one a very smooth road at low speed. Worse on bumpy roads. I've heard kyb don't last some gm are $135 not paying that. Just want a good replacement. Also wondering if these trucks use a bearing in the mount. From what I've found they don't but I'm new to the truck and don't know for sure. Plans are to go with lesjofors springs in front with Bilstein 4600 struts. In rear just swap in some 4600 shocks. Anything else you'd recommend doing? 260k on the dash.
