DIY Alignment Turn Plates

I admire your making what you need. I looked around for the longest time for plates....then ran an ad on a local online trading page.....almost a year later....man send a message that he has a set all boxed to ship but the buyer flaked and that was some time ago...said I could have them for a crisp 100.00 bill and as he was local, I jumped on them with all four feet....
