LCAs and Upper control arm bolt sizes....help

So i will be getting some LCAs and the upper to go with it. the only thing is i have heard you can not reuse the stock bolts and nuts. so i now need to get new nuts and bolts. but i am all sorts of confused when it comes down to 10.9 and 9.8 and 12mm or 14mm. someone who has gotten the bolts and installed them please help. and where do i get them? ive searched this forum as well as other forums and google. i cant seem to find a definite answer. any help will be greatly appreciated. thank you.

I recently did LCAs. I ordered these part numbers from fordparts.com

Front Bolt:W711504-S439
Front Nut:W710089-S440
Rear Bolt:W704888-S900
Rear Nut:W704991-S900

Each part number listed comes with 2 of each. So only order 1 of each part number.

Torque to 129 ft lbs.

Not sure about UCAs

Dude, you can reuse these. I track my car and reuse these bolts all the time and have had zero issues. use some red Loctite and you'll be good.

You can reuse the stock bolts but many after market kits come with their own bolts... At least all of the stuff I've put on did

I re-used all mine as well but didn't go hardcore with the red loctite, just used blue here.

For those of you wishing to purchase the bolts, the dealer wants almost $60, so I just ordered the list below for $28 + $11 shipping from "group1autoparts"
https://www.group1autoparts.com/index.php?p=home

You can also get them for a few dollars more from
Ford Parts Giant - Genuine OEM Ford Auto Parts

I hope someone else on here finds this information useful.

Rear Lower Control Arms (nuts and bolts)
Front Bolt: W711504-S439 Qty: 2
