Ansen scattershield

I purchased an Ansen steel scattershield along with the A833 for the conversion Im doing on my 360 powered 68 barracuda. The scattershield is stamped "meets SEMA specs" and "AHRA" and "NHRA". I know what all these things mean, but I cant find any info on the net about these scattershields. They dont seem to be manufactured anymore. Can anyone fill me in on what I've got here. Are these recent manufacture or ancient relics? Is it a good scattershield?
