windage tray in oil sump

I installed a windage tray  (I'm pretty sure it was the urs4 one) in my 3B,
which resides is an urquattro.  You need 2 oil pan gaskets and the windage
tray gets sandwiched in between.  You'll have to remove the oil pick-up
line - which requires about three hands to get back together with all those
gaskets and such.....anyway, you'll also need to ovalize some holes on the
back of the motor.  It's been a couple years since I did it so forgive me.
Here's the idea, with the windage tray and extra gasket, the oil pan is
lowered a couple mm, so some holes in back do not line up.  Luckily all it
requires is said ovalizing.  When you take a look back there hopefully it
will make sense.

Keep in mind this was on a 3B so YMMV
