4l80e check balls

Is there anything to drill on the 4L80E seperator plate like the TH400 (i was planning on doing that again and after rechecking I realized I was looking at the TH400 instructions).
Also - the hole to plug on the bottom of the case for finishing the dual feed mod, I have a 3/8" tap but the hole is a hair bigger, where can I get a plug for this ?
Also, what size is the plugs you have? My 3/8" tap seems to be pretty accurate but the hole in the bottom of the case is just a hair bigger so the tap does no good.
And I did read for the TH400 drilling the plate to .125 is ok, is that the same for the 4L80E or should I not touch that? Right now its just a basic rebuild, and the dual feed.
