Just got my tank guard delivered with removable hitch 
I have bolts to go through the chassis as I have jate rings there already, but need to get some bolts for the part that goes through the bumper...as circled..
Anyone know the correct size (width/length) of bolt needed so I can nip out at lunch time to get a couple?
Also can these be fitted without removing the bumper?
Cheers
