Help with size of bolts,washers NOT included w Borla touring exhaust 140404 cat-back

apparently there are a couple of bolts, washers, and nuts that weren't in the kit to install the Borla(read this in a post from (deinonychus). Do anybody knows the size to buy them before start this project at home today?. Any help will be appreciated. I have a ford raptor 2013 crewcab.

I got it, already removed the 13mm bolts and on my way to auto zone.

If needed for a newbie like me.I will use the stock bolts but you need to buy from AutoZone
the part#440600A (M10-1.50 class 8.8 HEX nuts) and the part#002740 (M10 class 10.9 flat washers) as this will be needed for installation of the Borla exhaust 140404 and not included in the kit.

I didi it,took almost 3 hours at home with basically no equipment except the tools described below. For future reference needed equipment:
1) 3/8” Drive Ratchet
2) 3/8” Drive Extension 3” (didn't used it in my case)
3)13mm and 15mm Deep Well Socket
4) Exhaust Removal Pliers(a must, $20, to be used for 10 seconds) vs a pry bar
5) from AutoZone the part#440600A (M10-1.50 class 8.8 HEX nuts) and the part#002740 (M10 class 10.9 flat washers) not included in the borla exhaust kit, I reused the bolts from the stock muffler assembly, if not you need to buy 2 new screws.
6) WD-40 or equivalent lubricant.
7) flat screwdriver
8)glasses and gloves
9) remove the spare tire and lift with the jack from the rear end.
10) 2 people required to do the job.
