Coast....did you see what I posted? Those rail road plates are hard as heck. They have four 1" square holes for the spikes, but the dimentions are right around 8"x12". They will weld together just fine. Contact your local railroad office, talk to one of the workers, (non office jockey), and they will give you some. Also old cutter bars work great. Just cut to length and weld them togeter. Not the nice cut outs Jeeps did, but you are not going to see any difference at 500+ yds.
