Both involve a substitution of metric for an SAE size.

1. I replaced the short extend and retract P/S hoses tonight.  My flare nut wrenches don't fit on the end that goes into the control valve so I had to use an open end wrench.  I think it's supposed to be 7/16" but on both those that I took off and the new ones I put on (delcos), an 11 mm fit much more snugly and allowed me to not round off the nuts.  

2. This one involves the diff fill plug.  I think a 5/8" open-end is the optimal tool here, but there's not much room to turn it with everything still installed.  A socket and ratchet with extension work much better, but I don't have square or 8 point sockets that big.  I tried some different 12 point socket sizes to see if there was one that would grab it snugly and ended up with (I think - it's been a week or two) 19 mm.  Worked perfectly to get it off without rounding and to snug it up again when I was done.  

Just thought I'd share - I'm sure there're other methods that work just as well or better!

I replaced my hoses also, from Corvette America. I used the S.A.E. flair nut wrench, and worked well, fit was exact. On the diff plug, I used a recessed plug. Does not have the shoulder on to hold the red tag, but you can use a 1/2 inch ratchet, or a extention of the same. Not sure what N.C.R.S. would say about it.
