Info for people looking at this in the future...
The stock oil pan bolts are 20mm and 50mm. There are two 20mm ones closest to the transmission. The AWR pan is thicker but your stock bolts should work... however I think 25mm and 55mm bolts would work best. Also, the pickup bracket bolt IS long enough but you need to put a spacer in between it and the block. You could get a bolt that is like 5mm longer if you wanted. Lastly, the part number for the gasket on the pickup is FS01-14-248 so you can have one in between the new spacer and the old one.
Maz2001MP, I checked it out the oil level situation today. From my guesstimate, you are right. The "full" mark on the dip-stick seems to be right at the very top of my fitting (which is as high as possible). However I did not test by filling the oil pan up with what, 5.3 quarts?
Anyways, looking at the main bearing support plate, it looks tough to get a fitting in there. The place where you would tap is kind of a valley, it is not flat. It doesn't seem like you'd be able to thread your fitting down so it is even close to being flush with the outside. Plus if you want to take the MBSP off, you need to remove your transmission, clutch, and flywheel to get the two bolts at the back! You could drill it and tap it while the pan is off, but it'd be tough. Doing all this stuff while the motor is out is so much nicer
Anyways, I haven't figured out what I'm going to do yet. The MBSP way seems better, but might be tough to pull off. Plus your line will be super short/awkward, so I'd have to remake return line #1,942 of this install. You'd probably be better off using a rubber hose like you are. You can get really heat resistant nice ones, they just don't have the tough stainless steel outside. Just make sure it doesn't rub on stuff.
And for returning to the pan, it is damn close. The oil level would be right at the top of the fitting with ALL the oil in the pan. I can't imagine when it'd be all in there, even with it off. A good amount is still dripping out of my motor. I don't know though, it'd definitely drain way better the other way. ARG!!!
I'll be sure to post back on what I do, and I'll take some pictures too.
