I picked up the washers today and made sure that the skid plate bolts fit through and that I could tighten the bolt with my 13mm socket. Good news is everything seems to fit!Agreed!
I will be installing the skid plates probably this weekend, so I'll update my build thread with pictures and a more detailed write up.
I, for one, am super happy to have found these. LP Adventures' price for rally washers is ridiculous. Heck, at ~$7 per washer, these aren't exactly cheap anyways.
