Hi,
I seem to remember someone making one out of plastic - maybe HDPE  1/2" thick or so.
I may have been Greyhawk.  If it does not come up and you can't find it in a search, you might inquire of him.
 
My 360 is up to 1444 hrs now without ever cracking the stock plates.  A clever mechanic suggested early on to make silicone rubber ridges on the frontplate so that there is supporting pressure there.  It must work.
