I used 5/32" thick !
I must of had mis-read or mis-understood something along the way. I thought you replaced your skid plate and used the oem skid plate for this. I suspect now, that you used left over pieces from the "new" skid plate. ??? The HDPE comes in 1/8" thickness choices. I did get an extra sheet of 1/8" in case there was a learning curve with the front flares. I'll choose which to go with once they come in and have the fender off.
