Holley Engine to transmission lower structure support vs. stock 4.7 support?

So I've had one on order through Holley for the last 6months and doesn't look like I'll be seeing it any time soon!?!
Holley 302-65 Holley Lower Structure Support for Gen III Hemi Engines and Transmissions


While looking for parts for the 545RFE trans that I'm using I cam across the stock 4.7 lower support mount and it looks exactly like the Holley part.
Has anybody tried fitting this or come across this part at anytime and could offer any info on this part? Its available and much less then the Holley part...
