Lower control arm nut/bolt fell off - 2000 yukon

[ekajkrats]

Hey all, the nut came off the lower control arm on my 2000 GMC Yukon XL on the driver side. The bolt then nearly fell out but I was alerted to it as it hit the bolt heads on the cv axle while I was driving home.

I was able to get the bolt back through and get a nut on it. The nut size is m16x2.0. I can order a new a/c delco bolt (ACDelco GM Genuine Parts 15733534 M16x2x140 Front Lower Suspension Control Arm Bolt) but not the nut. What grade and type nut should I get should I get?

And on the passenger side is this a stover cone nut with locking washer under it? I'll take it off and check the washer if someone here isn't sure but I'm still not sure on what/where to source the correct nut.

Thanks,
Jacob
