Thanks for all of the input! (and thanks for the shout-out Rick)
The tray above with the big holes was for reference as it got me thinking about the oil returns. The TechnoSump kit has the 996/997 swirl returns that do not have the big cans on the ends. Since I plan to use the 996/997 returns that came with the kit, I am not planning on cutting any holes in the horizontal baffle (as there aren't any holes in the TechnoSump/TunesRS kit or the LN Engineering kit).
Here is where I am today - this looks exactly like the LN/Bilt Racing kit (
Bilt Racing 2QT Deep Sump Oil Pan Kit inc. Pickup-Tube Extension, Windage Tray & X51 Baffle LN Engineering)
Please excuse my lack of fine metal working skills on the windage tray - I'm just a DIY hack. Installation tomorrow...
